Help me please! I need to make a loop that will read information from the file
function pushbutton1_Callback(hObject, eventdata, handles)
[file,path] = uigetfile('*.apa');
[file, ~] = fopen(fullfile(path,file));
fileinfo=dir(path);
filesize=fileinfo.bytes;
i=1
while (~feof(file)) && (ftell(file)<filesize)
a=fread(file,[1,1],'single');
b=fread(file,[1,1],'single');
addz=fread(file,[1,1],'single');
bitadd=fread(file,[1,1],'single');
if (addz==1)&&(bitand(bitadd,16))
ad(i)=a
bd(i)=b
for j=1:length(ad)
intaddora(j)=a(j)+1;
intaddorb(j)=a(j)-1;;
end
i=i+1
end
end
The first part opens the file and I want it to be immediately considered in the loop? , but in static text i = 1, i.e. the cycle does not count, please help me fix it

in some files you need to tighten checks (files were not written correctly)

You can enable breakpoints by clicking on the dash next to the line number in the editor.
