Python | sympy.Matrix.row_del() method

Last Updated : 12 Jun, 2019

With the help of sympy.Matrix.row_del() method, we can delete the rows of the matrix.

Syntax : sympy.Matrix().row_del() Return : Return a new matrix.

Example #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.

Python3 1=1

# 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)

Output :

Matrix([1, 2])

Example #2 :

Python3 1=1

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)

Output :

Matrix([[2, 3], [23, 45]])
