Herror T_sum_matrix(const Htuple MatrixID, const Htuple SumType, Htuple* MatrixSumID)

void SumMatrix(const HTuple& MatrixID, const HTuple& SumType, HTuple* MatrixSumID)

HMatrix HMatrix::SumMatrix(const HString& SumType) const

HMatrix HMatrix::SumMatrix(const char* SumType) const

Description

The operator sum_matrixsum_matrixSumMatrixSumMatrixSumMatrix returns the sum of the elements of the MatrixMatrixMatrixMatrixmatrix defined by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. A new matrix MatrixSumMatrixSumMatrixSumMatrixSummatrixSum is generated with the result and the matrix handle MatrixSumIDMatrixSumIDMatrixSumIDMatrixSumIDmatrixSumID of this matrix is returned. Access to the elements of the matrix is possible e.g. with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrix.

The type of sum determination of the matrix can be selected via the parameter SumTypeSumTypeSumTypeSumTypesumType:

'columns'"columns""columns""columns""columns":

The sum is returned for each column of the MatrixMatrixMatrixMatrixmatrix separately. The resulting matrix MatrixSumMatrixSumMatrixSumMatrixSummatrixSum has one row and the identical number of columns as the input matrix.

Example:

'rows'"rows""rows""rows""rows":

The sum is returned for each row of the MatrixMatrixMatrixMatrixmatrix separately. The resulting matrix MatrixSumMatrixSumMatrixSumMatrixSummatrixSum has the identical number of rows as the input matrix and one column.

Example:

'full'"full""full""full""full":

The sum is returned using all elements of the MatrixMatrixMatrixMatrixmatrix. The resulting matrix MatrixSumMatrixSumMatrixSumMatrixSummatrixSum has one row and one column.

Matrix handle of the input matrix.

SumTypeSumTypeSumTypeSumTypesumType (input_control)  string → HTupleHTupleHtuple (string) (string) (HString) (char*)

Type of summation.

Default value: 'columns' "columns" "columns" "columns" "columns"

MatrixSumIDMatrixSumIDMatrixSumIDMatrixSumIDmatrixSumID (output_control)  matrix → HMatrix, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Matrix handle with the sum of the input matrix.

Result

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