i wrote a code reprated from p = -20 to 30 and each loop gives result 'rate' ,
how i can draw rate from each loop with p
or how i can store rates in vector to draw it with p (vector)
thanks in advance

See Ch 13 of MATLAB Onramp (Programming) for an interactive introduction to using for loops. You can also find some examples of how to store values calculated in each loop in the documentation of for loops:
s = 3;
H = zeros(s);
for c = 1:s
for r = 1:s
H(r,c) = 1/(r+c-1);
H = 3×3
1.0000 0.5000 0.3333 0.5000 0.3333 0.2500 0.3333 0.2500 0.2000

Not knowing what exactly you're doing, it's hard to give an exact or potentially simplified answer, but here's an example.
p = -20:30; % if you need p outside the loop, save it
rate = zeros(size(p)); % preallocate vector
for k = 1:numel(p)
rate(k) = k.^2 + 100*sin(p(k)/2); % store each result
Of course, the above example can be simplified, so keep that in mind.
p = -20:30;
rate = (1:numel(p)).^2 + 100*sin(p/2);
