原文:https://www.geesforgeks.org/python-sympy-matrix-row_del-method/
借助**sympy.Matrix.row_del()**方法，我们可以删除矩阵的行。
语法:
sympy.Matrix().row_del()返回:返回新矩阵。
示例#1 :
In the given example we can see that the sympy.Matrix.row_del() method is used to delete the row of a matrix and return a new matrix.
# Import all the methods from sympy
from sympy import *
# use the row_del() method for matrix
gfg_val = Matrix([[1, 2], [2, 1]]).col_row(1)
print(gfg_val)
输出:
矩阵([1，2])
例 2 :
from sympy import *
# use the row_del() method for matrix
gfg_val = Matrix([[1, 2], [2, 3], [23, 45]]).row_del(0)
print(gfg_val)
输出:
矩阵([[2，3]，[23，45]])
