max_matrixT_max_matrixMaxMatrixMaxMatrixmax_matrix (Operator)

Name

max_matrixT_max_matrixMaxMatrixMaxMatrixmax_matrix — Returns the elementwise maximum of a matrix.

Signature

max_matrix( : : MatrixID, MaxType : MatrixMaxID)

Description

The operator max_matrixmax_matrixMaxMatrixMaxMatrixmax_matrix returns the maximum values of the elements of the Matrix defined by the matrix handle MatrixIDMatrixIDMatrixIDmatrixIDmatrix_id. A new matrix MatrixMax is generated with the result and the matrix handle MatrixMaxIDMatrixMaxIDMatrixMaxIDmatrixMaxIDmatrix_max_id of this matrix is returned. Access to the elements of the matrix is possible e.g., with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixget_full_matrix.

The type of maximum determination of the matrix can be selected via the parameter MaxTypeMaxTypeMaxTypemaxTypemax_type:

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

The maximum is returned for each column of the Matrix separately. The resulting matrix MatrixMax has one row and the identical number of columns as the input matrix.

Example:

MaxTypeMaxTypeMaxTypemaxTypemax_type = 'columns'"columns""columns""columns""columns"

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

The maximum is returned for each row of the Matrix separately. The resulting matrix MatrixMax has the identical number of rows as the input matrix and one column.

Example:

MaxTypeMaxTypeMaxTypemaxTypemax_type = 'rows'"rows""rows""rows""rows"

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

The maximum is returned using all elements of the Matrix. The resulting matrix MatrixMax has one row and one column.

Example:

MaxTypeMaxTypeMaxTypemaxTypemax_type = 'full'"full""full""full""full"

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 → (handle)

Matrix handle of the input matrix.

MaxTypeMaxTypeMaxTypemaxTypemax_type (input_control) string → (string)

Type of maximum determination.

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

List of values: 'columns'"columns""columns""columns""columns", 'full'"full""full""full""full", 'rows'"rows""rows""rows""rows"

MatrixMaxIDMatrixMaxIDMatrixMaxIDmatrixMaxIDmatrix_max_id (output_control) matrix → (handle)

Matrix handle with the maximum values of the input matrix.

Result

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