Python | sympy.Matrix().col_insert()

With the help of Matrix().col_insert() method, we can insert a column in a matrix having dimension nxm, where dimension of inserted column is nx1.

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

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

# Import all the methods from sympy
from sympy import *

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

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

print(new_mat)

Output :

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

Example #2 :

# Import all the methods from sympy
from sympy import *

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

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

print(new_mat)

Output :

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