Compute the determinant of a Two-Dimensional array in linear algebra in Python

PythonNumpyServer Side ProgrammingProgramming

To compute the determinant of a 2D array in linear algebra, use the np.linalg.det() in Python Numpy. The 1st parameter, a is the input array to compute determinants for. The method returns the determinant of a.

Steps

At first, import the required libraries-

import numpy as np

Create an array −

arr = np.array([[ 5, 10], [12, 18]])

Display the array −

print("Our Array...\n",arr)

Check the Dimensions −

print("\nDimensions of our Array...\n",arr.ndim)

Get the Datatype −

print("\nDatatype of our Array object...\n",arr.dtype)

Get the Shape −

print("\nShape of our Array object...\n",arr.shape)

To compute the determinant of a 2D array in linear algebra, use the np.linalg.det() in Python −

print("\nResult...\n",np.linalg.det(arr))

Example

import numpy as np

# Create an array
arr = np.array([[ 5, 10], [12, 18]])

# Display the array
print("Our Array...\n",arr)

# Check the Dimensions
print("\nDimensions of our Array...\n",arr.ndim)

# Get the Datatype
print("\nDatatype of our Array object...\n",arr.dtype)

# Get the Shape
print("\nShape of our Array object...\n",arr.shape)

# To compute the determinant of a 2D array in linear algebra, use the np.linalg.det() in Python Numpy.

# The 1st parameter, a is the input array to compute determinants for.

# The method returns the determinant of a.
print("\nResult...\n",np.linalg.det(arr))

Output

Our Array...
[[ 5 10]
[12 18]]

Dimensions of our Array...
2

Datatype of our Array object...
int64

Shape of our Array object...
(2, 2)

Result...
-30.000000000000014
