sqrt_matrixsqrt_matrixsqrt_matrixSqrtMatrixSqrtMatrix (Operator)

Name

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

Signature

sqrt_matrix( : : MatrixID : MatrixSqrtID)

The operator sqrt_matrixsqrt_matrixsqrt_matrixSqrtMatrixSqrtMatrix computes the square root values of all elements of the input MatrixMatrixMatrixMatrixmatrix given by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. A new matrix MatrixSqrtMatrixSqrtMatrixSqrtMatrixSqrtmatrixSqrt is generated with the result. The operator returns the matrix handle MatrixSqrtIDMatrixSqrtIDMatrixSqrtIDMatrixSqrtIDmatrixSqrtID of the matrix MatrixSqrtMatrixSqrtMatrixSqrtMatrixSqrtmatrixSqrt. 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:

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

Example:


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

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.

MatrixSqrtIDMatrixSqrtIDMatrixSqrtIDMatrixSqrtIDmatrixSqrtID (output_control) matrix → (integer)

Matrix handle with the square root values of the input matrix.

Result

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