Matlab Coder : Size Mismatch Issue
显示 更早的评论
Hi,
I am using MATLAB coder to generate mex files for the matlab. Here is one error I am getting in line
x2_est_sym = x2_est_sym.';
Size mismatch (size [64 x 1] ~= size [:? x 64]).
The size to the left is the size of the left-hand side of the assignment.
Any idea.

You should create a new Question for that.

As C is statically typed, MATLAB Coder needs to compute a static type for all variables in the program, which also involves computation of the size. MATLAB Coder sets the size of a variable when it is first used. As the variable x2_est_sym is used in the right hand side and its size at that point is (presumably) [64x1], its size is set to that value. The size of the expression x2_est_sym' is however [:?x64]. When you try to assign it back to x2_est_sym, there is a size mismatch.
It is hard to suggest a fix without looking at more of your code, but can you just use a different variable on the left hand side?
