CALL MULT Routine

Calculates the multiplicative product of two input matrices.

Category:	Matrix Operations
Requirement:	The number of columns for the first input matrix must be the same as the number of rows for the second matrix.

Syntax

Example

Syntax

CALL MULT(X, Y, Z);

Required Arguments

X: specifies an input matrix with dimensions m x n (that is, X[m, n]).

Y: specifies an input matrix with dimensions n x p (that is, Y[n, p]).

Z: specifies an output matrix with dimensions m x p (that is, Z[m, p]), such that

Example

The following example uses the MULT CALL routine:

options pageno=1 nodate;

proc fcmp;
   array mat1[2,3] (0.3, -0.78, -0.82, 0.54, 1.74, 1.2);
   array mat2[3,2] (1, 0, 0, 1, 1, 0);
   array result[2,2];
   call mult(mat1, mat2, result);
   put result=;
quit;

Output from the MULT CALL Routine
