So here's my code:
function Ratio = findit(fc)
for M = 1:200;
gains = dtmf_filt_char(M,fc,0); %dtmf_filt_char is a funtion
gain_ratio(gains); %gain_ratio is a funtion that I made
M = M +1;
Basically, I want to store all the results of gain_ratio(gains) into a vector so I can plot it against M. Can anyone help? Thanks.
