CALL ADDMATRIX Routine

Performs an elementwise addition of two matrices or a matrix and a scalar.

Category:	Matrix Operations
Requirement:	All input and output matrices must have the same dimensions.

Syntax

Example

Syntax

CALL ADDMATRIX(X, Y, Z);

Required Arguments

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

Y: specifies an input matrix with dimensions m x n (that is, Y[m, n]) or a scalar.

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

Example

The following example uses the ADDMATRIX CALL routine:

proc fcmp;
   array mat1[3,2] (0.3, -0.78, -0.82, 0.54, 1.74, 1.2);
   array mat2[3,2] (0.2, 0.38, -0.12, 0.98, 2, 5.2);
   array result[3,2];
   call addmatrix (mat1, mat2, result);
   call addmatrix (2, mat1, result);
   put result=;
quit;
