How do I Compare Matrices in Proc IML

[Sanscrit_2prov]

I would like to compare every row of matrix x (let's say 200 by 29) with each row of matrix y (150,29) one at a time.

So for example row 1 in X compared to rows 1 to 150 in y  to see if they both elements equal 1. If yes, set new matrix to 1.

Something like below:

do i=1 to 200;

  do j=1 to 150;

does x[i,]=y[j,] ? if yes new matrix say z[i,}=1;

end;

end;

z would have 200 rows and 29 columns.

The question isn't clear.

So for example row 1 in X compared to rows 1 to 150 in y to see if they both elements equal 1.

What does "if they both elements equal 1" mean?

z would have 200 rows and 29 columns.

Wouldn't the result be (150*200)x1?

Post some data and output you want could better explain your question !!

proc iml;
x={1 0,
   0 1,
   1 1};
y={1 1,
   1 1};

z=j(nrow(x),1,.);
do i=1 to nrow(x);
  if all(x[i,]=y) then z[i]=1;
end;
print z;
quit;
