Inferred size ('[1 13]') for data ***** (#32) does not match back propagated size ('[13]') from Simulink.

Hi, I am using embedded Matlab function block in Simulink. Function returns the row vector from input matrix (NxN).

function y=RowVector(x)
     y =(x(1,:));
end

Following error is received: Inferred size ('[1 13]') for data *** (#32) does not match back propagated size ('[13]') from Simulink.

Can you help me in resolving this error? Regards Swapnil

Answer 1

[Shailesh Raturi]

hello. step 1- click right on Matlab function and go to Explore. step 2 - there click on y, right side in general there will be size block. there is -1 written step 3- change that to [1 3] you will no get now no error njoy!!

Thank you, it was resolved. Your explanation was good :)

Answer 2

[Walter Roberson]

y = zeros(13, 1);
y(:) = x(1,:);

Answer 3

Can you try y=x(1,:)';?

Answer 4

[swapnil]

I have tried with y =x(1,:); It was just typo mistake. But it doesn't work.

[Fangjun Jiang]

No, I meant with the transpose.

[craq]

the transpose doesn't work for me. I tried transposing inside the Embedded Matlab Function and with a simulink block between the Embedded Matlab Function and the DeMux.
