REMOVE
This procedure implements the remove operation.
Usage
The REMOVE stored procedure has the following syntax:
- REMOVE(matrixAname,matrixBname,matrixCname)
- Parameters
- matrixAname
- The name of input matrix A.
- matrixBname
- The name of input matrix B, containing the indexes of elements to be removed from matrix A.
- matrixCname
- The name of output matrix C, a row vector of matrix A with removed elements.
Details
If matrices A and B, specified by the parameters, are considered row vectors, the second matrix indicates which elements of the first matrix are to be removed. The output is a row vector. Matrix C must not exist prior to the operation.
Examples
CALL nzm..shape('21,32,13,34,55,56,27,68,79',3,3,'A');
CALL nzm..shape('1,15,5,7',2,2,'B');
CALL nzm..remove('A','B','C');
CALL nzm..print('A');
CALL nzm..print('B');
CALL nzm..print('C');
CALL nzm..delete_matrix('A');
CALL nzm..delete_matrix('B');
