Hey there,
I want to get a s-function with Simulink Coder out of a BMS_strategy_EJ04_Diagmodel. when i run the model,it tell me :"Error(s) encountered while building model "BMS_strategy_EJ04_Diagmodel"".
The detail of the error message:

BMS_strategy_EJ04_Diagmodel.mk:171: D:/Program: No such file or directory

gmake: *** No rule to make target `Files/MATLAB/R2011brtwctoolslcctools.mak’. Stop.

Well, it seems the path in line 171 is not working right. so i hope you can help me to slove this problem.
thank you !!

I have a .mat file that contains various signals and their corresponding values. I also have a model file that contains similar signal names in inport blocks, which are connected to a subsystem. However, the values of these signals in the model file differ from the values in the .mat file.My task is to match the signals of the inport blocks to the signals in the .mat file. If a signal is present in both files, I need to assign the .mat signal and its value to the corresponding inport block in the model. Instead of using the inport block, I need to use a Signal Builder block (or a similar block that I’m not currently aware of).The reason for using a Signal Builder block is that it allows me to assign both the signal value and time to the block. This way, I can directly test the model by running it.In the input files, I will provide:
A model file containing inport blocks
A .mat file
I will write a script that compares the signals in the model file with the signals in the .mat file. If any signals in the model file match the signals in the .mat file, the script will assign the .mat signal values to the corresponding Signal Builder blocks in the model.After making these changes, I will store the updated model file separately without modifying the original model file. it is possible to perform this task and how ?I have a .mat file that contains various signals and their corresponding values.

Hi,
I am doing the installation of the ROS 2 Dashing and Gazebo as seen here
I am wokring on windows and have the VM installed and sucessfully have the ros_melodic_dashing_gazebov9.vmx operating.

When trying to use the worlds on my desktop, they simply open a terminal windows for a split second and then close again. It seems that they crash or Gazebo runs into issues and fails to open any of the worlds.
I have also tried this in conjunciton with the differetial drive example here . Which indicates to use
export SVGA_VGPU10=0
before opening the world, however this does not work either.

Any suggestions as to what is the problem?

Thanks,

Does MATLAB not support multiplying and transposing block symbolic matrices? For instance, the following multiplication and transpose are not evaluated on the individual matrices inside of the block matrices:
syms A B C D E F G H [2 2] matrix
X = [A B;C D].’
Y = [A B;C D]*[E F;G H]
The outputs I am expecting are:
X = [A.’ C.’;B.’ D.’]
Y = [A*E+B*G A*F+B*H;C*E+D*G C*F+D*H]Does MATLAB not support multiplying and transposing block symbolic matrices? For instance, the following multiplication and transpose are not evaluated on the individual matrices inside of the block matrices:

Hi,
I have a function "Func" that takes 2 inputs, 1 from each a different matrix (A and B). The matrices have same number of rows, but different number of columns.
My output matrix, C, takes the summation of Func’s output. For the entire row of matrix B, we will keep A constant. We will only go onto the next value of A when the B row is done. Additionally, we keep the rows the same such that only row 1 matrix B values will be used with row 1 A values. Row 2 matrix B with row 2 matrix A. etc. Here’s the demo code showing what I need it to do:
A = [1, 2, 3, 4;
5, 6, 7, 8;
9, 10, 11, 12];

B = [13, 14;
15, 16;
17, 18];

% Notes:
% Input A is a 3×4 matrix
% Input B is a 3×2 matrix
% Output C is going to be same dimensions as A, 3×4
% Function "Func" takes in inputs from A and B. syntax =
% Func(input from A, input from B)

% Example of how this is supposed to look:
% C(1,1) = Func(1,13) + Func(1,14)
% Above meaning the 1,1 entry of C matrix is the summation of the output of function "Func" where the inputs is A(1,1) and B(1,1) and B(1,2)
% C(1,2) = Func(2,13) + Func(2,14)
% C(1,3) = Func(3,13) + Func(3,14)
….
% C(2,1) = Func(5,15) + Func(5,16)
% Now that we are in the 2nd row, the "Func" function uses inputs A(2,1) and B(2,1) and B(2,2)
% C(2,2) = Func(6,15) + Func(6,16)
….
% C(3,1) = Func(9,17) + Func(9,18)
….
% C(3,4) = Func(12,17) + Func(12,18)
I know how to do this brute force, but I am struggling with how to approach this problem:
How many for loops do I need? (I currently have 2)
How do I get the loop to calculate the summation? Right now, my loop is only calculating the instaneous value, not summing.

I am trying to plot the suplots in the for loop using the following code:

% some code

if PWM_switch == 1
ax1 = axes(t);
ax1.Layout.Tile = Test_Case;
if mod_switch == 1
if OpenLoop == 0
plot(table.data(:,1), table.data(:,2), ‘k’); hold on;
elseif OpenLoop == 1
plot(table.data(:,1), table.data(:,2), ‘k–‘); hold on;
end
end
if mod_switch == 4
if OpenLoop == 0
plot(table.data(:,1), table.data(:,2), ‘r’); hold on;
elseif OpenLoop == 1
plot(table.data(:,1), table.data(:,2), ‘r–‘); hold on;
end
end
end
end
but it appears that every time ax1 = axes(t) is executed, the supplot gets overlapping. You can still see old y-axis scales, but only the latest plots. When I run the loop step-by-step, all plots are plotted in the correct subplots; only they are overlapping.
I need to switch between subplots based on the conditions, i.e., Test Cases.
ax1.Layout.Tile = Test_Case correctly locates the subplot.
