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