Answer to the question in the subject line:
B = zeros( size(A) );
and see the documentation on size.

So zeros(a1,a2) creates a matrix of zeros with a1 rows and a2 columns, for example:
a=0 0 0
0 0 0
So code pp=zeros(1,size(r,2)); will create matrix pp with 1 row and size(r,2) columns. As long as size(r,2 ) is the number of columns of matrix r, size of pp will be equal to size of r.
Size(r,1) is number of rows in matrix r
Size(r,2) is number of columns
