I have some problem with plotting.
Basically I have a vector
a=1:0.2:10
for n=1:1:length(a)
while ... %a bunch of calculations using a(n)
b(n)=b(n)+1
end
end
I want to plot b against a, so I wrote
plot(a,b)
but it doesn't plot the results I got by entering values individually-- when I didn't have the outer for loop . Could somebody please help?
Thank you.

@per isakson: There isn't an error message. It plots something, but not the right thing...

@Richard: Put the code in a function and debug your code. Set a break point on the first line and step line by line. Check the values. The problem is hardly with the plot command. Try plot(a,b,'.').
