How to perform complex calculation in matlab

How would I go about performing calculations using complex numbers? Below is the equation I'm trying to implement

E = V + X*I

Where V = 1 , X = 2j and I = 25 at an angle of 10. I want to be able to do it in terms of the variables since V, X and I are user inputs

Representing complex numbers in matlab is easy and straight forward. Read more here: https://in.mathworks.com/help/matlab/complex-numbers.html

z = 1 + 3*1i ;  % make a complex number 
R = real(z)     % Extract real part of Z
I = imag(z)     % Extract imaginary part of Z
A = abs(z) ;    % GEt absolute of complex number

V = 1;
X = 2j;
I = 25;
E = V + X .* I;

If the user is expected to input X without the 'j' part then just

V = 1;
X = 2;
I = 25;
E = V + X*1j .* I;
