norm_matrix — 矩阵的范数。
算子 norm_matrix computes the norm of the elements
of the Matrix defined by the matrix handle
MatrixID. The return value is a floating point number.
The type of norming of the matrix can be selected via the parameter
NormType:
The Frobenius norm
is computed. 结果的计算公式为：
with m = number of rows and n = number of columns of the
Matrix.
示例：
The infinity norm is
computed. The result is the largest value of the sum of the
absolute values of the elements of the rows. The formula for the
calculation is:
with m = number of rows and n = number of columns of the
Matrix.
示例：
The 1-norm is computed. The
result is the largest value of the sum of the absolute values of
the elements of the columns. The formula for the calculation is:
with m = number of rows and n = number of columns of the
Matrix.
示例：
The 2-norm is computed. The
result is the largest singular value of the Matrix. 结果的计算公式为：
示例：
MatrixID (输入控制) matrix → (handle)
输入矩阵的矩阵句柄。
NormType (输入控制) string → (string)
Type of norm.
默认值： '2-norm'
值列表： '1-norm', '2-norm', 'frobenius-norm', 'infinity-norm'
Value (输出控制) real → (real)
Norm of the input matrix.
如果参数有效，算子 norm_matrix 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
