why can't i map this function?

r=1:0.5:9;

i=0.5:0.5:4.5; n=12;

p=1./(n*log(1+0.01.*i));

t=log(r).*p;

figure; plot(r,t); xlabel('r');ylabel('t');

You can’t plot it because ‘r’ is (1x17) and ‘p’ is (1x9). You cannot multiply vectors whose lengths are not the same, at least the way you have written your code.

thank you so much!

As always, my pleasure!

If you want to create them both to be the same lengths, with different increments (or ‘step length’), you can use the linspace function.
