Hello,

I have a problem in Matlab Coder.

* Here is the test file * * :A_in = magic(3);A_out = My_Func (A_in);
* And here is the funcion :* *function A_out = My_Func (A_in) [r, c] = size (A_in); a = double(repmat (A_in(1,:), 1, 1)); b = double(repmat (A_in(r,:), 1, 1)); Atemp = [a; double(A_in); b]; d = repmat(Atemp(:,1), 1, 1); e = repmat(Atemp(:,end), 1, 1); Atemp1 = [d Atemp e]; Atemp_all= []; for I = 1:3 for J = 1:3 f = Atemp1(I:I+r-1,J:J+c-1); Atemp_all= double (cat (3, Atemp_all, f)); end; end; A_out = median (Atemp_all,3);end

Running it in Matlab is OK. But trying to build My_Func_mex causes the next error:

Dimension 1 is fixed on the left-hand side but varies on the right ([0 x 0] ~= [:? x :? x :?])

Can you help me please? Thanks
