Due to the large collection of Python libraries, we can implement almost all MATLAB operators in Python. Let’s look at a few examples.

Multiplication, division, and power operators

MATLAB has several operators for performing multiplication, division, and power operations on arrays. The . operator performs the element-wise operations, For example:

C++
var1 = [2,3;4,5]
var2 = [2,1;3,2]
disp("Multiplication of two matrices (var1 * var2)");
disp(var1*var2);
disp("Multiplication of corresponding elements (element by element var1 * var2)");
disp(var1.*var2);
disp("Division of two matrices (var1 * (var2^-1))");
disp(var1/var2);
disp("Division of corresponding elements (element by element var1/var2)");
disp(var1./var2);
disp("Division of two matrices ((var1^-1)*var2)"); 
disp(var1\var2);
disp("Division of corresponding elements (element by element var2/var1)");
disp(var1.\var2);
disp("Cube of a matrix (var1 * var1 * var1)");
disp(var1^3);
disp("Element wise power of matrix");
disp(var1.^3);

The table below shows how the above MATLAB operations can be performed in Python using NumPy ...
