mean_matrixT_mean_matrixMeanMatrixMeanMatrix (Operator)

Name

mean_matrixT_mean_matrixMeanMatrixMeanMatrix — Returns the elementwise mean of a matrix.

Signature

mean_matrix( : : MatrixID, MeanType : MatrixMeanID)

Description

The operator mean_matrixmean_matrixMeanMatrixMeanMatrixMeanMatrix returns the mean values of the elements of the MatrixMatrixMatrixMatrixmatrix defined by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. A new matrix MatrixMeanMatrixMeanMatrixMeanMatrixMeanmatrixMean is generated with the result and the matrix handle MatrixMeanIDMatrixMeanIDMatrixMeanIDMatrixMeanIDmatrixMeanID 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 mean determination of the matrix can be selected via the parameter MeanTypeMeanTypeMeanTypeMeanTypemeanType:

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

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

Example:

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

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

Example:

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

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

Example:

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

MatrixIDMatrixIDMatrixIDMatrixIDmatrixID (input_control) matrix → (handle)

Matrix handle of the input matrix.

MeanTypeMeanTypeMeanTypeMeanTypemeanType (input_control) string → (string)

Type of mean determination.

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

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

MatrixMeanIDMatrixMeanIDMatrixMeanIDMatrixMeanIDmatrixMeanID (output_control) matrix → (handle)

Matrix handle with the mean values of the input matrix.

Result

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