`numpy:matrix`

source: /dev/numpy/build-install/usr/lib/python3.14/site-packages/numpy/__init__.py

Signature

staticmethod def matrix ( data , dtype = None , copy = True )

Summary

Returns a matrix from an array-like object, or from a string of data.

Extended Summary

A matrix is a specialized 2-D array that retains its 2-D nature through operations. It has certain special operators, such as * (matrix multiplication) and ** (matrix power).

Parameters

data : array_like or string: If data is a string, it is interpreted as a matrix with commas or spaces separating columns, and semicolons separating rows.
dtype : data-type: Data-type of the output matrix.
copy : bool: If data is already an ndarray, then this flag determines whether the data is copied (the default), or whether a view is constructed.

Examples

import numpy as np
a = np.matrix('1 2; 3 4')
a
