# Matrix minimization by row (retained)

Hi there,

I´m using IML/SAS in SAS Enterprise Guide.

Is there any solution that allows us to obtain Matrix B after apply retained minimization on Matrix A by row (see below)?

Thank you very much!

``````proc iml;
A ={
94 19 89 73 78 33 87 73  8 85 80 43  0,
92 95 69 64 32 11 30 18 11 75 82 48 99,
34 92 58 80 24 68 34 98 87 41 18 34  5};

B = A;
do j = 2 to ncol(A);
B[,j] = (B[,j-1] >< B[,j]);
end;
print B;``````
