Generally speaking , Matrix multiplication in user-defined functions will be normal ……
Test1
function y = fcn(u)
A = rand(4,3);
y = A*u;
But my friend did have this problem when he was writing , Here's the picture , The input is a 31 Matrix , In the custom function with a 43 Matrix multiplication of , It's still a 4*3 Matrix
The back is really not good , Accept the custom function by x Calculation Ax Become output A, Module calculation using matrix multiplication Ax, To make it work properly
I don't know what magic operation this is, but it may have something to do with other modules , But it's complicated
