problem in using plot function

hi,all i want plot time axes from 1 to 5 second against theta axes from 5 to 90 but i get error t=[1:0.25:5]; >> th=[5:5:90]; >> plot(t,th) ??? Error using ==> plot Vectors must be the same lengths.

>>how i can overcome this error thanks in advance

Type

numel(th)  % result is 17
numel(t)   % result is 18

the two vectors must have the same number of elements

Try this now

 t=1:0.25:5;
 th=5:5:numel(t)*5;
 plot(t,th)
