sub_matrixT_sub_matrixSubMatrixSubMatrixsub_matrix (Operator)

Name

sub_matrixT_sub_matrixSubMatrixSubMatrixsub_matrix — Subtract two matrices.

Signature

sub_matrix( : : MatrixAID, MatrixBID : MatrixSubID)

Description

The operator sub_matrixsub_matrixSubMatrixSubMatrixSubMatrixsub_matrix computes the difference of the input matrices MatrixAMatrixAMatrixAMatrixAmatrixAmatrix_a and MatrixBMatrixBMatrixBMatrixBmatrixBmatrix_b given by the matrix handles MatrixAIDMatrixAIDMatrixAIDMatrixAIDmatrixAIDmatrix_aid and MatrixBIDMatrixBIDMatrixBIDMatrixBIDmatrixBIDmatrix_bid. Both matrices must have identical dimensions. A new matrix MatrixSubMatrixSubMatrixSubMatrixSubmatrixSubmatrix_sub is generated with the result. The operator returns the matrix handle MatrixSubIDMatrixSubIDMatrixSubIDMatrixSubIDmatrixSubIDmatrix_sub_id of the matrix MatrixSubMatrixSubMatrixSubMatrixSubmatrixSubmatrix_sub. Access to the elements of the matrix is possible e.g. with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrixget_full_matrix. The formula for the calculation of the result is: MatrixSubMatrixSubMatrixSubMatrixSubmatrixSubmatrix_sub = MatrixAMatrixAMatrixAMatrixAmatrixAmatrix_a - MatrixBMatrixBMatrixBMatrixBmatrixBmatrix_b.

Example:

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

MatrixAIDMatrixAIDMatrixAIDMatrixAIDmatrixAIDmatrix_aid (input_control) matrix → (handle)

Matrix handle of the input matrix A.

MatrixBIDMatrixBIDMatrixBIDMatrixBIDmatrixBIDmatrix_bid (input_control) matrix → (handle)

Matrix handle of the input matrix B.

MatrixSubIDMatrixSubIDMatrixSubIDMatrixSubIDmatrixSubIDmatrix_sub_id (output_control) matrix → (handle)

Matrix handle with the difference of the input matrices.

Result

If the parameters are valid, the operator sub_matrixsub_matrixSubMatrixSubMatrixSubMatrixsub_matrix returns the value TRUE. If necessary, an exception is raised.
