名称

mean_matrixT_mean_matrixMeanMatrixMeanMatrixmean_matrix — 返回矩阵的元素平均值。

签名

mean_matrix( : : MatrixID, MeanType : MatrixMeanID)

描述

算子 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.可通过算子 get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrixget_full_matrix 等方式访问该矩阵的元素。

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.

示例：

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.

示例：

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.

示例：

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