Description

The operator get_value_matrixget_value_matrixGetValueMatrixGetValueMatrixget_value_matrix returns the values of one ore more elements of the Matrix as a tuple of floating point numbers. The Matrix is given by the matrix handle MatrixIDMatrixIDMatrixIDmatrixIDmatrix_id. The row coordinates of the elements of the Matrix are determined by the tuple RowRowRowrowrow, the column coordinates by the tuple ColumnColumnColumncolumncolumn.

Example:

RowRowRowrowrow = [0,2,1], ColumnColumnColumncolumncolumn = [1,0,3]

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

MatrixIDMatrixIDMatrixIDmatrixIDmatrix_id (input_control)  matrix → HMatrix, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Matrix handle of the input matrix.

RowRowRowrowrow (input_control)  integer(-array) → HTupleMaybeSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Row numbers of matrix elements to be returned.

Default: 0

Suggested values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 50, 100

Restriction: Row >= 0

ColumnColumnColumncolumncolumn (input_control)  integer(-array) → HTupleMaybeSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Column numbers of matrix elements to be returned.

Default: 0

Suggested values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 50, 100

Restriction: Column >= 0

ValueValueValuevaluevalue (output_control)  real(-array) → HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)

Values of indicated matrix elements.

Result

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