Not sure if it is what you are trying to do, but you can extract the real and imaginary parts of an expression using the real() and imag() functions.
That is because you want to plot only the magnitude of the DFT coefficients, or the magnitudes squared

An imaginary number iy can be added to a real number x to form a complex number z, as in z = x + iy. Here x is called the real part and y is called the imaginary part of the complex number z (we often write this as x = Re(z) and y = Im(z)). For example, a complex...
MATLAB produces the following figure. The complex number is drawn as a circle here, denoted by the “o” argument (lower case letter o, not a zero!) that is supplied to the plot command. Note that the x axis corresponds to the real part of the complex number, whereas the y axis corr...

Exponentials first arise out of a need for a shorthand for multiplication (much like multiplication itself can be seen as a generalization of a shorthand for addition). Lets say we have a numberawhich we've multiplied together a bunch of times to getb: ...
These are pretty long expressions, and subs() of your linspace into them can take a long long time because it is going to try to find the algebraic number in each case. In practice you would matlabFunction() the formulae ... keeping in mind that there...
An optimized MATLAB code providing rapid computation with high accuracy is presented. Keywords: Voigt function; complex error function; high-accuracy approximation; Taylor expansion Graphical Abstract 1. Introduction The complex error function, also known as the Faddeeva function, is given by: [1,2...
