sqrt_matrix_modsqrt_matrix_modsqrt_matrix_modSqrtMatrixModSqrtMatrixMod (Operator)

Name

sqrt_matrix_modsqrt_matrix_modsqrt_matrix_modSqrtMatrixModSqrtMatrixMod — Compute the square root values of the elements of a matrix.

The operator sqrt_matrix_modsqrt_matrix_modsqrt_matrix_modSqrtMatrixModSqrtMatrixMod computes the square root values of all elements of the input MatrixMatrixMatrixMatrixmatrix given by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. The input matrix is overwritten with the result. 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:

                ___________
               |
  Matrix =   \ |  Matrix    .
        ij    \|        ij

Example:


           / 3.0  1.0  2.0 \               / 1.7321   1.0000   1.4142 \
  Matrix = | 5.0  7.0  2.0 |  ->  Matrix = | 2.2361   2.6458   1.4142 |
           \ 9.0  4.0  1.0 /               \ 3.0000   2.0000   1.0000 /

Attention

sqrt_matrix_modsqrt_matrix_modsqrt_matrix_modSqrtMatrixModSqrtMatrixMod modifies the content of an already existing matrix.

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.

Result

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