Let say, I want to create this pattern. Value of D and beta are known. Beta is a delay. When applied to input step down, it should follow the input, but with a delay of beta.Let say, I want to create this pattern. Value of D and beta are known. Beta is a delay.

Coupled ODEs by ode45 and could not get the figures
Hi everyone!
I’ve been learning MATLAB for about six months, so I apologize if I ask any basic questions. In part of my project, I have a system of six coupled ODEs (all functions of t). You can refer to the attached picture for more details.
To obtain the T profile in terms of t, I decided to define the function similarly to how many others do:
function dYdt = complexSystem(t, Y)
Aa = 1e14; % Pre-exponential factor for xa
Ea = 2.24e-19; % Activation energy for xa
Ac = 4e13; % Pre-exponential factor for xc
Ec = 2.03e-19; % Activation energy for xc
As = 1e15; % Pre-exponential factor for xs
Es = 2.24e-19; % Activation energy for xs
Aec = 1e12; % Pre-exponential factor for xec
Eec = 1.4e-19; % Activation energy for xec
Kb = 1.38e-23; % Boltzmann constant
z0 = 0.033; % Initial value for z
ma = 0.13;
ha = 1.714e6;
mc = 0.29;
hca = 3.14e5;
hs = 2.57e5;
C = -3600 * 1.1 * 3.0 * (1-0.12-0.51);
T = Y(1);
Xa = Y(2);
Xc = Y(3);
Xs = Y(4);
Z = Y(5);
Soc = Y(6);
dXadt = -Aa * Xa * exp(-Ea/(Kb*T));
dXcdt = Ac * Xc * exp(1 – Xc) * exp(-Ec / (Kb * T));
dXsdt = -As * Xs * exp((-Z / z0) * (-Es / (Kb * T)));
dZdt = Aa * Xs * exp((-Z / z0) * (-Es / (Kb * T)));
dSocdt = -Aec * (1 – Xc) * Xa * exp(-Eec / (Kb * T));
Qa = -ma * ha * dXadt;
Qc = -mc * hca * dXcdt;
Qs = -ma * hs * dXsdt;
Qec = C * dSocdt;
Q = Qa + Qc + Qs + Qec;
dTdt = Q;
dYdt = [dTdt; dXadt; dXcdt; dXsdt; dZdt; dSocdt];
end
Then, I defined the initial conditions and solved the ODEs using ode45.
% Initial conditions
Y0 = [298; 0.75; 0.04; 0.015; 0.0331; 0]; % [T0; Xa0; Xc0; Xs0; Z0; Soc0]
% Time span
tspan = [0 100000];
% Solve ODEs
[T, Y] = ode45(@(t, Y) complexSystem(t, Y), tspan, Y0);
Lastly, I attempted to plot the results. However, the code took forever to run, and I didn’t get any figures from it.
Could my initial conditions be incorrect? Or are my ODEs not converging?
Thank you so much for your time and help!

Aa = 1e14; % Pre-exponential factor for xa
Ea = 2.24e-19; % Activation energy for xa
Ac = 4e13; % Pre-exponential factor for xc
Ec = 2.03e-19; % Activation energy for xc
As = 1e15; % Pre-exponential factor for xs
Es = 2.24e-19; % Activation energy for xs
Aec = 1e12; % Pre-exponential factor for xec
Eec = 1.4e-19; % Activation energy for xec
Kb = 1.38e-23; % Boltzmann constant
z0 = 0.033; % Initial value for z
ma = 0.13;
ha = 1.714e6;
mc = 0.29;
hca = 3.14e5;
hs = 2.57e5;
C = -3600 * 1.1 * 3.0 * (1-0.12-0.51);
T = Y(1);
Xa = Y(2);
Xc = Y(3);
Xs = Y(4);
Z = Y(5);
Soc = Y(6);
dXadt = -Aa * Xa * exp(-Ea/(Kb*T));
dXcdt = Ac * Xc * exp(1 – Xc) * exp(-Ec / (Kb * T));
dXsdt = -As * Xs * exp((-Z / z0) * (-Es / (Kb * T)));
dZdt = Aa * Xs * exp((-Z / z0) * (-Es / (Kb * T)));
dSocdt = -Aec * (1 – Xc) * Xa * exp(-Eec / (Kb * T));
Qa = -ma * ha * dXadt;
Qc = -mc * hca * dXcdt;
Qs = -ma * hs * dXsdt;
Qec = C * dSocdt;
Q = Qa + Qc + Qs + Qec;
dTdt = Q;
dYdt = [dTdt; dXadt; dXcdt; dXsdt; dZdt; dSocdt];
end
Then, I defined the initial conditions and solved the ODEs using ode45.
% Initial conditions
Y0 = [298; 0.75; 0.04; 0.015; 0.0331; 0]; % [T0; Xa0; Xc0; Xs0; Z0; Soc0]
% Time span
tspan = [0 100000];
% Solve ODEs
[T, Y] = ode45(@(t, Y) complexSystem(t, Y), tspan, Y0);
Lastly, I attempted to plot the results. However, the code took forever to run, and I didn’t get any figures from it.
Could my initial conditions be incorrect? Or are my ODEs not converging?
Thank you so much for your time and help!

ylabel(‘State Variables’) Hi everyone!
I’ve been learning MATLAB for about six months, so I apologize if I ask any basic questions. In part of my project, I have a system of six coupled ODEs (all functions of t). You can refer to the attached picture for more details.
To obtain the T profile in terms of t, I decided to define the function similarly to how many others do:
function dYdt = complexSystem(t, Y)

dZdt = Aa * Xs * exp((-Z / z0) * (-Es / (Kb * T)));
dSocdt = -Aec * (1 – Xc) * Xa * exp(-Eec / (Kb * T));
Qa = -ma * ha * dXadt;
Qc = -mc * hca * dXcdt;

Trouble With MATLAB Variable Creation
Hello! I would like to dynamically read in data and assign data values from a text file.
Here is the text file:
object crop_image.nii
plane 3
coeff -5.046e-19 3.168e-13 -5.716e-8 0.005 2.746
amax 1
nfact 1
pt .9906
suvr 1
regi 1
Initially, I was reading it in using this block of code (which works).
readin = readlines(insert text file name here);
for i = 1:length(readin)
this = split(readin(i))’;
switch this(1)
case ‘object’
object = this{2};
case ‘plane’
plane = str2double(this{2});
case ‘coeff’
coeff = str2double(this(2:end));
case ‘suvr’
suvr = str2double(this{2});
case ‘amax’
amax = str2double(this{2});
case ‘nfact’
nfact = str2double(this{2});
case ‘pt’
pt = str2double(this{2});
case ‘regi’
regi = str2double(this{2});
otherwise
fprintf(‘Invalid delimiter: %s! Please check your text file.n’, this{1});
return;
end
end
But a huge switch case doesn’t really give polish. I guess it shouldn’t matter if the code works, but still. I’d like it to be more refined.
Oh, yeah, the reason for all the cell array stuff (and for the huge switch case) is because I’ll be running this code (this code is a portion of a much larger script) from Linux. Also, the text file isn’t guaranteed to come in the order of object, plane, coeff, etc., which is why I have the code detect the first word.
Anyway, I thought I could solve my issue using the assignin function, but it’s not working? Here’s what I have so far.
if ismember(this(1), ["object", "plane", "coeff", "suvr", "amax", "nfact", "pt", "regi"])
if isa(this(2), ‘string’)
assignin(‘base’, this(1), this(2));
else
assignin(‘base’, this(1), str2double(this(2:end)));
end
else
fprintf(‘Invalid delimiter: %s! Please check your text file.n’, this(1));
return;
end
I’ve done my best to debug. The code is not skipping over the assignin function. That line of code is executing, but when it executes, nothing happens.
Like, I’ve checked the values of this(1) and this(2) right before the script calls the assignin function. Yes, this(1) equals "object" and this(2) equals the object name, also a string, but nothing shows up when the assignin line of code executes. I don’t get it. Would appreciate any and all suggestions.

Array Filter not working as expected
This flow works with one glitch. If there were two schools with the same date (which is probable) then, the violations for each school are being included in the email for both schools.
Here is the code for my filter:
{
“type”: “Query”,
“inputs”: {
“from”: “@outputs(‘Get_items_-_All_Violations_from_30_days_ago’)?[‘body/value’]”,
“where”: “@equals(items(‘Apply_to_each_-_for_each_”Get_Item”‘)?[‘School’],variables(‘Unique School’))”
},
“runAfter”: {
“Set_variable_-_Unique_School”: [
“Succeeded”
]
},
“metadata”: {
“operationMetadataId”: “86fb4366-e227-42eb-bf2b-07d9219c316d”
}
}
The string variable at the point where the filter is occurring has only one school in the string and I’ve been able to confirm things on the data side. The data is good.
Thanks for any help that can be offered.

Billing Account Type can only be ‘US Exempt’?

Been a partner for years. Now I apparently must create a Billing Account (and Profile). When I attempt to create a new ‘Billing Account’ most of the information is correctly populated with my company’s information. However, when I enter the firm’s EIN (TAX ID) then I see under it that ‘Type’ only has the option ‘US Exempt’. My company is not tax exempt.

Can not know how to use minibatchqueue for a deep learning network that takes input as 4-D numbers and output 3 numbers through fully-connected layer.
There is a MATLAB example that uses minibatchqueue for input date as 4-D (image) and output as categorical. What I need is to update this example to accept output to be three numberical values (through a 3-fully connected layer).
The MATLAB example is:
[XTrain,YTrain] = digitTrain4DArrayData;
dsX = arrayDatastore(XTrain,IterationDimension=4);
dsY = arrayDatastore(YTrain);
dsTrain = combine(dsX,dsY);
classes = categories(YTrain);
numClasses = numel(classes);
net = dlnetwork;
layers = [
imageInputLayer([28 28 1],Mean=mean(XTrain,4))
convolution2dLayer(5,20)
reluLayer
convolution2dLayer(3,20,Padding=1)
reluLayer
convolution2dLayer(3,20,Padding=1)
reluLayer
fullyConnectedLayer(numClasses)
softmaxLayer];
net = addLayers(net,layers);
net = initialize(net);
miniBatchSize = 128;
mbq = minibatchqueue(dsTrain,…
MiniBatchSize=miniBatchSize,…
PartialMiniBatch="discard",…
MiniBatchFcn=@preprocessMiniBatch,…
MiniBatchFormat=["SSCB",""]);
function [X,Y] = preprocessMiniBatch(XCell,YCell)
% Extract image data from the cell array and concatenate over fourth
% dimension to add a third singleton dimension, as the channel
% dimension.
X = cat(4,XCell{:});
% Extract label data from cell and concatenate.
Y = cat(2,YCell{:});
% One-hot encode labels.
Y = onehotencode(Y,1);

Again, what I need is to know how to modify the code to accept three regression values at fully connected output layer.
Actually, I tried alot and alot without success. I think the main trick is the update that should be done inside this function: preprocessMiniBatch (defined above).
ThanksThere is a MATLAB example that uses minibatchqueue for input date as 4-D (image) and output as categorical. What I need is to update this example to accept output to be three numberical values (through a 3-fully connected layer).
The MATLAB example is:
[XTrain,YTrain] = digitTrain4DArrayData;
dsX = arrayDatastore(XTrain,IterationDimension=4);
dsY = arrayDatastore(YTrain);
dsTrain = combine(dsX,dsY);
classes = categories(YTrain);
numClasses = numel(classes);
net = dlnetwork;
layers = [
imageInputLayer([28 28 1],Mean=mean(XTrain,4))
convolution2dLayer(5,20)
reluLayer
convolution2dLayer(3,20,Padding=1)
reluLayer
convolution2dLayer(3,20,Padding=1)
reluLayer
fullyConnectedLayer(numClasses)
softmaxLayer];
net = addLayers(net,layers);
net = initialize(net);
miniBatchSize = 128;
mbq = minibatchqueue(dsTrain,…
MiniBatchSize=miniBatchSize,…
PartialMiniBatch="discard",…
MiniBatchFcn=@preprocessMiniBatch,…
MiniBatchFormat=["SSCB",""]);
function [X,Y] = preprocessMiniBatch(XCell,YCell)
% Extract image data from the cell array and concatenate over fourth
% dimension to add a third singleton dimension, as the channel
% dimension.
X = cat(4,XCell{:});
% Extract label data from cell and concatenate.
Y = cat(2,YCell{:});
% One-hot encode labels.
Y = onehotencode(Y,1);

Warning: Matrix is singular, close to singular or badly scaled. Results may be inaccurate. RCOND = NaN
These data are already preprocessed so they are already syncronized and they are of the same size. However, when I tried running, MATLAB says: Matrix is singular, close to singular or badly scaled. Results may be inaccurate. RCOND = NaN. What seems to be the problem with this and how can this be fixed?

Formula based on a combination of two other cells where the combination varies
Hello forum friends
I need a formula that will look at two other cells and depending on the combination in those cells populate the third cell. For example:
If A1 says Critical and B1 says High then C1 will = Priority 1.
For example, the combinations will be as follows:
A1B1C1 (cell with the formula)CriticalHighPriority 1Critical MediumPriority 2Critical LowPriority 3Urgent High Priority 1Urgent MediumPriority 2Urgent LowPriority 3RoutineHighPriority 2Routine MediumPriority 3Routine LowPriority 4
Thanks in advance for your help!
