can you help me? thank you

Here:
0.5:0.1/20:0.6

Here:
0.5:0.1/20:0.6
Beacuase: (0.6 - 0.5)/20

Oleg is correct: length( 0.5:0.1/20:0.6 ) is 21. You really should use linspace if you want a linear sequence with a specified number of elements. That's what it's there for.

You haven't really specified if you want a sequence or just a set of numbers. Picking up on your term 'generate', perhaps you meant this:
randarr = @(lo, hi, n) lo + (hi-lo) * rand(1,n);
data = randarr(0.5, 0.6, 22);
That creates a bunch of random numbers in your specified range. Note I've wrapped it in an anonymous function to give the same syntax as linspace.

Oops, just realised I specified that anonymous function incorrectly. Fixed.
