Hi all,
I have an array of numbers (generated using the colon operator):
x=1.198:0.1:2.198
This gives me:
x = 1.198 1.298 1.398 1.498 1.598 1.698 1.798 1.898 1.998 2.098 2.198
I would however like to have a random number between 0 and 5 (including 0 and 5) in the place of 9 which is repeating in the second decimal place for all the above numbers.
Is there any way to do it?
Thanks

Something like this is about the noise you want to see in that digit. If it is too large, then multiply by a little smaller number at the end.
x=1.198:0.1:2.198;
x = x + (rand(size(x)) - 0.5)*0.01
x = 1×11
1.1933 1.2968 1.4000 1.5026 1.5942 1.6965 1.7949 1.8946 2.0029 2.1001 2.1972
