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

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