Python | sympy.Matrix().row_insert()

With the help of Matrix().row_insert() method, we can insert a row in a matrix having dimension nxm, where dimension of inserted row is 1xm.

Syntax : Matrix().row_insert()
Return : Return a new matrix.

Example #1 :
In this example, we are able to insert a row in a matrix by using Matrix().row_insert() method.

# Import all the methods from sympy
from sympy import *

# Make a matrix
gfg_mat = Matrix([[1, 2], [2, 1]])

# use the row_insert() method for matrix
new_mat = gfg_mat.row_insert(1, Matrix([[3, 4]]))

print(new_mat)

Output :

Matrix([[1, 2], [3, 4], [2, 1]])

Example #2 :

# Import all the methods from sympy
from sympy import *

# Make a matrix
gfg_mat = Matrix([[1, 2], [2, 1]])

# use the row_insert() method for matrix
new_mat = gfg_mat.row_insert(2, Matrix([[13, 24]]))

print(new_mat)

Output :

Matrix([[1, 2], [2, 1], [13, 24]])
