min_matrixmin_matrixMinMatrixMinMatrix (Operator)

Name

min_matrixmin_matrixMinMatrixMinMatrix — Returns the elementwise minimum of a matrix.

Herror min_matrix(const Hlong MatrixID, const char* MinType, Hlong* MatrixMinID)

Herror T_min_matrix(const Htuple MatrixID, const Htuple MinType, Htuple* MatrixMinID)

void MinMatrix(const HTuple& MatrixID, const HTuple& MinType, HTuple* MatrixMinID)

HMatrix HMatrix::MinMatrix(const HString& MinType) const

HMatrix HMatrix::MinMatrix(const char* MinType) const

HMatrix HMatrix.MinMatrix(string minType)

Description

The operator min_matrixmin_matrixMinMatrixMinMatrixMinMatrix returns the minimum values of the elements of the MatrixMatrixMatrixMatrixmatrix defined by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. A new matrix MatrixMinMatrixMinMatrixMinMatrixMinmatrixMin is generated with the result and the matrix handle MatrixMinIDMatrixMinIDMatrixMinIDMatrixMinIDmatrixMinID 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 minimum determination of the matrix can be selected via the parameter MinTypeMinTypeMinTypeMinTypeminType:

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

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

Example:

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

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

Example:

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

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