Thread Subject: Between Random number

Hi all,
I would like to determine a random number between two defined numbers; example a random number between 5 and 10.
For example in MS excel I used randbetween(5,10) and it returns a random number between 5 and 10. I would like to perform the same operation in MATLAB but couldnot find the syntax.
I am very new to MATLAB.
I would appreciate if any help.

Regards,
Subrat.

Note that that will return a random number that is -strictly- between 5 and 10
and will never be -exactly- 5 or -exactly- 10.

Also note that the number so calculated will have a uniform random distribution,
(to within one part in 2^53).

Thank you so much. It works.

Since the help for RANDBETWEEN says that it generates random integers, if
you're using release R2008b, use the new RANDI function.

Alternately, shift and scale the output of RAND to the desired range, then
use FIX, FLOOR, CEIL, or ROUND to round the shifted and scaled output to
integers.

Steve:
That randi function looks very nice. I just tried it out. It's sure
to become useful. (Don't know why it took so long, but thanks for
finally adding it.)
