Description

The operator mean_matrixmean_matrixMeanMatrixMeanMatrixMeanMatrixmean_matrix returns the mean values of the elements of the Matrix defined by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixIDmatrix_id. A new matrix MatrixMean is generated with the result and the matrix handle MatrixMeanIDMatrixMeanIDMatrixMeanIDMatrixMeanIDmatrixMeanIDmatrix_mean_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 mean determination of the matrix can be selected via the parameter MeanTypeMeanTypeMeanTypeMeanTypemeanTypemean_type:

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

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

Example:

MeanTypeMeanTypeMeanTypeMeanTypemeanTypemean_type = 'columns'"columns""columns""columns""columns""columns"

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

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

Example:

MeanTypeMeanTypeMeanTypeMeanTypemeanTypemean_type = 'rows'"rows""rows""rows""rows""rows"

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

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

Example:

MeanTypeMeanTypeMeanTypeMeanTypemeanTypemean_type = 'full'"full""full""full""full""full"
