CALL SUBTRACTMATRIX Routine
Performs an element-wide subtraction of two matrices
or a matrix and a scalar.
| Category: |
Matrix Operations |
| Requirement: |
All input and output matrices must have the same dimensions. |
Syntax
CALL SUBTRACTMATRIX(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 SUBTRACTMATRIX CALL routine:
options pageno=1 nodate;
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 subtractmatrix (mat1, mat2, result);
call subtractmatrix (2, mat1, result);
put result=;
quit;
Output from the SUBTRACTMATRIX CALL Routine
The SAS System 1
The FCMP Procedure
result[1, 1]=1.7 result[1, 2]=2.78 result[2, 1]=2.82 result[2, 2]=1.46
result[3, 1]=0.26 result[3, 2]=0.8
