Hi, I am trying to use 'disp([num2str(A)])' command to name a graph.
I have a constant 'a' and a power 'n' on the formula: y = a.*x.^n I try to num2str this in my plot with the following syntax:
text(1,1, ['y = ' (num2str(a)) 'x^' (num2str(n)) ])
What happens is that only the first digit of n get raised up. a is 2.0003 and n is 0.49961, i get:
y = 2.0003x^(0) .49961
I only made it look as I want it to when i instead of num2str wrote:
text(1,1, ['y = ' (num2str(a) 'x' '^0^.^4^9^9^6^1']) which... just doesn't make a very good solution.
Thanks in advance!
