ANY Function

ANY (matrix);

The ANY function returns a value of 1 if any of the elements in matrix are nonzero. If all the elements of matrix are zero or missing, the ANY function returns a value of 0.

You can use the ANY function to compare elements in two matrices, as shown in the following statements: 

a = {1 2, 3 4};
b = {3 2, 1 0};
if any(a=b) then
   msg = "for some element, a[i,j] equals b[i,j]";
else
   msg = "a ^= b";
print msg;

msg
for some element, a[i,j] equals b[i,j] 




            

            


            
In the preceding statements, the IF-THEN expression is true if at least one element in a is the same as the corresponding element in b. You can use the ALL
                function to compare all of the elements in two matrices.
