N doesn't increase in 'for loop'

z=1:100; for n=1:100 f(z)=n; end

why f(z) all equals to 101 instead of 1, 2, 3...100 after running.

Answer 1

[Sean de Wolski]

t = zeros(1,10);
t(1:10) = 3

This is what you're doing. You're setting all of the indices (1:100) equal to n. Thus only the last iteration of the for-loop actually matters.

You probably want something like

for n = 1:100
  f(n) = n;
end
