sum_matrixT_sum_matrixSumMatrixSumMatrixsum_matrix (Operator)

Name

sum_matrixT_sum_matrixSumMatrixSumMatrixsum_matrix — Returns the elementwise sum of a matrix.

Signature

sum_matrix( : : MatrixID, SumType : MatrixSumID)

Description

The operator sum_matrixsum_matrixSumMatrixSumMatrixSumMatrixsum_matrix returns the sum of the elements of the MatrixMatrixMatrixMatrixmatrixmatrix defined by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixIDmatrix_id. A new matrix MatrixSumMatrixSumMatrixSumMatrixSummatrixSummatrix_sum is generated with the result and the matrix handle MatrixSumIDMatrixSumIDMatrixSumIDMatrixSumIDmatrixSumIDmatrix_sum_id of this matrix is returned. Access to the elements of the matrix is possible e.g. with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrixget_full_matrix.

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

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

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

Example:

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

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

Example:

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

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

Example:

Execution Information
