i have 2 matrix which have have same size.. if 1st matrix is size 5 the 2nd will also will be 5 if the 1st matrix is size 10 the 2nd will be 10
for example
%1st matrix
DF = [NaN 4 6 ;
3 NaN 5 ;
5 4 NaN ] ;
%2nd matrix
W = [6 10 5 ;
9 7 3 ;
1 4 8 ];
% PROBLEM SIZE (NUMBER OF SITES OR DEPTS)
pr_size = size(DF,1);
how do i code matrix W as pr_size? because W will be follow DF size?

You can initialize with

W = zeros(size(DF));

or with

 W = 0 * DF;
