code to extract real part of complex numbers in matlab

To extract the real part of a complex number in MATLAB, you can use the real function.

Here is an example code that extracts the real part of a complex number:

main.m
z = 3 + 4i; % define a complex number
real_part = real(z); % extract the real part
disp(real_part); % display the real part
124 chars
4 lines

This code will produce the following output:

main.m
3
2 chars
2 lines

In this example, z is a complex number with a real part of 3 and an imaginary part of 4. The real function is used to extract the real part of z and store it in the variable real_part. Finally, the disp function is used to display the value of real_part.

Note that if you have a matrix or an array of complex numbers, the real function will extract the real part of each element in the matrix or array.
