Hi,
Could someone explain a strange thing happend in my simple code?
numwl='11';
chieuchimd='1';
dwl=str2double(chieuchimd)/(str2double(numwl)-1);
mwl=[0:dwl:str2double(chieuchimd)]*1000;
text3={};
for i=1:str2double(numwl)
text3=[text3;{sprintf('%d',i-1)} {sprintf('DN%d',i-1)} {sprintf('%d',mwl(i))}]
end
When for-loop at i=4, the 3rd colum of the cell had a number that its format different with others.
I also search but had no answers.
Thanks

This is because mwl is not exactly 300 but 300 + 5.6843e-014.
Either use
mwl = round([0:dwl:str2double(chieuchimd)]*1000);
or
mwl = [0:dwl*1000:str2double(chieuchimd)*1000];
