Hi, Im going through old programs and ran into a problem. I build a function called lnz_co for lanczos filters but it has been erased from my library can someone help me out? the function sets up as follows:
[md,nd]=size(v); %%where v is a vector
fo=0; %% initial frequency
fc=1/48; %%cut off frequency
fn=1/2; %%Nyquist frequency
lp=200; %%not sure what this is
df=1/md;
f=lnz_co(fo,fc,fn,lp,df);
Please help
