Python sympy | matrix.column space()方法
原文:https://www.geesforgeks.org/python-sympy-matrix-column space-method/
借助症状。矩阵()。columnspace() 方法，我们可以找到一个矩阵的 Columnspace。矩阵()。columnspace() 返回跨越矩阵列空间的列向量列表。
语法:矩阵()。columnspace()
返回:返回跨越矩阵列空间的列向量列表。
示例#1:
# import sympy
from sympy import *
M = Matrix([[1, 0, 1, 3], [2, 3, 4, 7], [-1, -3, -3, -4]])
print("Matrix : {} ".format(M))
# Use sympy.columnspace() method
M_columnspace = M.columnspace()
print("Columnspace of a matrix : {}".format(M_columnspace))
输出:
Matrix : Matrix([[1, 0, 1, 3], [2, 3, 4, 7], [-1, -3, -3, -4]])
Columnspace of a matrix : [Matrix([
[ 1],
[ 2],
[-1]]), Matrix([
[ 0],
[ 3],
[-3]])]
例 2:
# import sympy
from sympy import *
M = Matrix([[14, 0, 11, 3], [22, 23, 4, 7], [-12, -34, -3, -4]])
print("Matrix : {} ".format(M))
# Use sympy.columnspace() method
M_columnspace = M.columnspace()
print("Columnspace of a matrix : {}".format(M_columnspace))
输出:
Matrix : Matrix([[14, 0, 11, 3], [22, 23, 4, 7], [-12, -34, -3, -4]])
Columnspace of a matrix : [Matrix([
[ 14],
[ 22],
[-12]]), Matrix([
[ 0],
[ 23],
[-34]]), Matrix([
[11],
[ 4],
[-3]])]
