What data type is the matrix? Should the empty matrix have the same data type?

Are you trying to make the matrix as null matrix or want to replace the elements with zeros(erasing the values). In the former case just use A=[];

Several options, depending on the desired result (same class, for instance):
A = []
A(:) = []
A = zeros(0,0,class(A))
