You can't fit 41 numbers into a slot meant for 1. Perhaps you meant this:
clear all
close all
clc
t=[0:0.5:20];
ip=zeros(12,22)
q=0.25;
Vp=0.25;
p0=0.25;
S=0.25;
alpha=0.25;
d=0.25;
dabs=0.25;
t_p=0.25;
for n = 1 : length(t)
this_t = t(n);
thisTerm = (q*Vp*p0*S)/(alpha*d)*(exp(-alpha*Vp*(this_t-t_p))-exp(-alpha*dabs));
ip(n)= thisTerm;
ipp=ip(n);
ipf=fft(ipp);
end
