Name

abs_matrixabs_matrixabs_matrixAbsMatrixAbsMatrix — Compute the absolute values of the elements of a matrix.

Signature

abs_matrix( : : MatrixID : MatrixAbsID)

The operator abs_matrixabs_matrixabs_matrixAbsMatrixAbsMatrix computes the absolute values of all elements of the input MatrixMatrixMatrixMatrixmatrix given by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. A new matrix MatrixAbsMatrixAbsMatrixAbsMatrixAbsmatrixAbs is generated with the result. The operator returns the matrix handle MatrixAbsIDMatrixAbsIDMatrixAbsIDMatrixAbsIDmatrixAbsID of the matrix MatrixAbsMatrixAbsMatrixAbsMatrixAbsmatrixAbs. Access to the elements of the matrix is possible e.g. with the operator get_full_matrixget_full_matrixget_full_matrixGetFullMatrixGetFullMatrix. The formula for the calculation of the result is:

  MatrixAbs    =   | Matrix   |.
           ij              ij

Example:


           /   3.0   1.0  -2.0  \                  /  3.0  1.0  2.0  \
  Matrix = |  -5.0   7.0   2.0  |  ->  MatrixAbs = |  5.0  7.0  2.0  |
           \  -9.0  -4.0   1.0  /                  \  9.0  4.0  1.0  /

Parallelization

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

Parameters

MatrixIDMatrixIDMatrixIDMatrixIDmatrixID (input_control) matrix → (integer)

Matrix handle of the input matrix.

MatrixAbsIDMatrixAbsIDMatrixAbsIDMatrixAbsIDmatrixAbsID (output_control) matrix → (integer)

Matrix handle with the absolute values of the input matrix.

Result

If the parameters are valid, the operator abs_matrixabs_matrixabs_matrixAbsMatrixAbsMatrix returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
