I am trying to introduce a new variable that is in terms of a variable that is known.
where r is just a row vector going from -15:15, r'' is the new variable, b&a are the unknown,real constants.
Ultimately I am trying to express a gaussian function in terms of the r=(-a/b)*r'', and take fft's of these gaussian functions.
I have tried using:
syms r'' a b
however when I am trying to take fft's, matlab is unable to do this because a, b, and r'' are syms.
I can't think of another way to introduce this new variable, maybe after the fft of the gaussian is taken? Below is the code I am using but an error comes up at the last two lines. Any help will be appreciated
clear syms r'' a b real r=-15:15; r=-(a/b)*r''; h=gaussmf(r,[(0.5)/(2*sqrt(2*log(2))),0]); g=gaussmf(r,[(0.1)/(2*sqrt(2*log(2))),0]); H=fft(h); G=fft(G);
