global nfile A flag
[fil pth]=uigetfile('.dat','Enter File Name Wich You Want to Work')
file=[pth fil];
fid=fopen(file,'r');
nfile=fread(fid);
nfile=imresize(nfile,[183 1]);% it is for compression?
axes(handles.axes1)
plot(nfile,'-'), title('Original Signal')
figure(1),plot(nfile,'-'), title('Original Signal')
z=zeros(100,1);
A=[z;nfile;z]; %it is filter?
axes(handles.axes2)
plot(A,'-'),title('Original Signal With Pad')
figure(2),plot(A,'-'),title('Original Signal With Pad')
flag=2;

It's not a filter. It simple resizes the signal to be exactly 183 elements long and slaps 100 zeros on either end of it. I don't know why they wanted/needed to do that. The only way you could say it was a filter was if the signal was longer than 183 elements and you squeezed it down - that's like a low pass filter but I don't think their intent was so much low pass filtering as it was resizing.
