Dears,
I have a matrix A(3200,3), I want to repeat each element (not repeat the matrix)in this matrix 200 times.
Thank you

A = reshape(repmat(A(:)',200,1),[],3);
This repeats the elements in the columns. If you want to repeat the along the rows do this:
A = reshape(repmat(reshape(A',[],1),1,200)',[],size(A,1))';
(Corrected)

That code I gave you has one more transpose than is necessary. You can do it this way instead:
A = reshape(repmat(reshape(A',1,[]),200,1),[],size(A,1))';
