Why I can not sign in in the installed matlab? (2024b academic version)
Hi I can not sign in in the installed matlab, when I try the sign in window write this:
mw-login :: No endpoint specified.
This is problem, because the toolboxes, wich I installed are not working, because the matlab do not see my lisence. But when I open online the matlab, the toolboxes are working.

Forcing robustfit to return an intercept
Hi,
I have datasets where I am plotting variance as a function of mean. The datasets have substantial heteroscedasticity but don’t really have high leverage outliers, as they are symmetric and n is large. I have Python code which uses HuberRegressor from sklearn.linear_model to fit a straight line. This works and I attach example below (from Python).
I am seeking to replicate this fit in MATLAB but have failed to get an intercept. I began with robustfit with the huber parameter. Whilst I get a line, the intercept is returned as zero with an SE of zero. So it is refusing to fit this parameter. In Python I get an intercept value. I tried various ways to get an intercept in MATLAB but all failed:
Adding a column of zeros to X and disabling the intercept in the CLI options of robustfit.
All the different fit types in robustfit.
Weighting the points in way similar to that in my short Python function. (https://github.com/datajoint/anscombe-numcodecs/blob/main/src/anscombe_numcodecs/estimate.py around line 63)
I tried fitlm both with and without the robust fit option.
All of the above result in a zero intercept. The only thing that gives me an intercept value is centering the X values around their mean. However, the fit fails badly on some datasets when I do this so I would like to avoid it. I have had no fit failures on the same data in Python.
I suspect what is happening is that the extreme heteroscedasticity makes the in SE of the intercept value very unreliable and MATLAB is somehow then choosing to avoid returning a value for it and sets it to zero. I don’t really care about the SE and significance, but I do need the intercept because I go on to use that value. Any idea how to force MATLAB to return it?Hi,

Intended Re-definition of parameters in simulink, overshadowing of parameter values
In C-Code there is a way to define a parameter using the #ifndef pre-processor directive. Is there a way to replicate this mechanism in Simulink, using data dictionaries?
For example, assume a vehicle system consisting of various subsystems. For this example assume a brake control system and an engine control system. To perform their calculations, both systems require to know the parameter "VehicleMass", so they define it as a parameter in their models. However, when they get integrated in a higher level vehicle model, the "VehicleMass" should best be described on the vehicle model level, to avoid incompatible / inconsistent definitions. But if it is define on vehicle model level, from my understanding it is currently required to first delete the lower level definitions, in order to avoid re-definition failures.
That causes another issue though, because if either of those lower level models is meant to be re-used, it can not be guaranteed that the top level integration model will always provide this value. What if the lower level model is meant to be standalone?
In C-Code, #ifndef checks if a value is already defined. If yes, that higher value is used. If no, a definition is done at this level. This mechanism prevents the issue described above.
In addition to parameters, I am experiencing the same issue with datatype definitions, so the lower level models use a given enum, but that enum might also be available in an integration environment.In C-Code there is a way to define a parameter using the #ifndef pre-processor directive.

Find least binary palindrome greater than a natural number
I am looking for an efficient way to generate the least binary number, b, that yields a natural number greater than a given natural number, d.
A small example would be d = 15, binary = 1111, and for which the least largest b = 10001 (decimal value 17).
Assume the natural number of interest, d, is 1 quadrillion (10^15) for which the binary representation, b, is:
‘11100011010111111010100100110001101000000000000000’
I have tried one standard approach from the literature, which is to form the sum b + reverse(b) and check to see if the
result is a palindrome that yields a natural number that is just above d. So far, after many cycles, that hasn’t produced anything.
There is no guarantee this method will always work, for example, it fails for the number 196.

Grey box model of 1d heat diffusion in a rod (official mathworks example)

I’m thinking about grey-box modelling of heat diffusion in a rod with the 1d heat equation.
There is a interesting example at mathworls side:

I would adapt the example (image: original) and change it a little bit to include a a convection to air at the left end of the rod (image: adapted).
Here is the code for the original version with the insulation at one end:
function [A,B,C,D,K,x0] = heatd(kappa,htf,T,Ngrid,L,temp)
% ODE file parameterizing the heat diffusion model
% kappa (first parameter) – heat diffusion coefficient
% htf (second parameter) – heat transfer coefficient
% at the far end of rod
% Auxiliary variables for computing state-space matrices:
% Ngrid: Number of points in the space-discretization
% L: Length of the rod
% temp: Initial room temperature (uniform)
% Compute space interval
deltaL = L/Ngrid;
% A matrix
A = zeros(Ngrid,Ngrid);
for kk = 2:Ngrid-1
A(kk,kk-1) = 1;
A(kk,kk) = -2;
A(kk,kk+1) = 1;
end
% Boundary condition on insulated end
A(1,1) = -1; A(1,2) = 1;
A(Ngrid,Ngrid-1) = 1;

I’m thinking about grey-box modelling of heat diffusion in a rod with the 1d heat equation.
There is a interesting example at mathworls side:
https://de.mathworks.com/help/ident/ug/estimate-continuous-time-grey-box-model-for-heat-diffusion.html?status=SUCCESS
I would adapt the example (image: original) and change it a little bit to include a a convection to air at the left end of the rod (image: adapted).
Here is the code for the original version with the insulation at one end:
function [A,B,C,D,K,x0] = heatd(kappa,htf,T,Ngrid,L,temp)
% ODE file parameterizing the heat diffusion model
% kappa (first parameter) – heat diffusion coefficient
% htf (second parameter) – heat transfer coefficient

% Auxiliary variables for computing state-space matrices:
% Ngrid: Number of points in the space-discretization
% L: Length of the rod
% temp: Initial room temperature (uniform)
% Compute space interval
deltaL = L/Ngrid;
% A matrix
A = zeros(Ngrid,Ngrid);

A(kk,kk-1) = 1;

Superimpose scatter data points on line charts in loop
Hi team. I have a simple script which takes in stock ticker from the my list and downloads histrorical data and then plots it on line chart (X axis is date, and Y axis is close price). I want to add scatter points on the dates when I bought securities. Example – If I bought stock A on 1/2/25 and 5/2/25 then I want my codes to show two dots on the line chart on these two dates. I know scatter needs second dimension so the x value will be the dates and y value should be what is there already on the line chart. I have attached a figure of what I want to achieve.
I have a list of securities (as shown in the image column "Name"), I would like to know best way to create a list for the dates that I want as scatters (as shown in image column "Purchased (scatter)"). Please advise how to create a list of dates which can have single or multiple dates for each securities (as shown in the image below). So when loop runs for security A it should then check for all dates for A and plot them as scatter before moving to security B in second iteraton. So total number of main loop iterations would be equal to number of securities I have in Name column.
My current code takes name from the list, downloads historical prices and then plots them on line chart in Loop.
Any help would be appreciated.

How to perform 2-way repeated-measures Manova using RepeatedMeasuresModel?
Hi,
I’m currently stuck on performing a two-way repeated-measures Manova in Matlab using the RepeatedMeasuresModel. My data set consists of six units, from each of which I measured three properties, which might be highly correlated. Each unit was tested using two within-subject factors each of which has two levels (4 conditions in total). Thus, my data table consists of six rows and twelve columns (3 properties * 4 conditions).
I created the within-table as follows:
within = table({‘A’;’A’;’A’;’A’;’B’;’B’;’B’;’B’;’C’;’C’;’C’;’C’},…
{‘1′;’2′;’1′;’2′;’1′;’2′;’1′;’2′;’1′;’2′;’1′;’2’},…
{‘a’;’a’;’b’;’b’;’a’;’a’;’b’;’b’;’a’;’a’;’b’;’b’},…
‘VariableNames’,{‘Property’,’Condition1′,’Condition2′});
The table looks like:
Property Condition1 Condition2
________ __________ __________

The repeated-measures Model I created using
rm = fitrm(t,’M1-M12~1′,’withinDesign’,within);
where t is the data table and M1-M12 are the responses.
If I now use
manova(rm)
the output looks like this:
Statistic Value F RSquare df1 df2 pValue
_________ _______ ___ _______ ___ ___ ______
Pillai 0.54237 0 0.54237 6 0 NaN

I don’t know, how I can specify, which of my within-subject factors are the different properties and which ones are the different conditions.
