numpy.mat() Method
The numpy.mat() method interprets the given input as a matrix. It is equivalent to numpy.matrix(). It does not make a copy of the data if the data is already a matrix or a ndarray.
Syntax
numpy.mat(data, dtype=None)
Parameter(s)
- data: Represents the input data of array_like type.
- dtype: Represents the type of the output matrix.
Return Value
It returns data interpreted as a matrix.
Example of numpy.mat() method in Python
# Import numpy
import numpy as np
# Creating a numpy array
arr = np.array([[1, 2], [3, 4]])
# Display original array
print("Original Array:\n",arr,"\n")
# Creating a matrix using mat
res = np.mat(arr)
# Display result
arr[0,0] = 5
print("Result:\n",res)
