Unique Random Integer List

A simple function that produce unique random Integer List

Description

Usage r=myrand(a,b)
a and b is the range, for example if we want to generate random integers between 370 and 55780 we call the function :
    r=myrand(370,55780)
We can also limit the list as we need. for example if we want only 10 random integers between 370 and 55780 we use:
r10=r(1:10;
It is also useful for scrambling an array randomly.

Should be
"for i=1:(b-a)+1" not

"for i=1:(b-a)" otherwise the final element in the array will never change from value of b

Hi Jan, Thanks for your comment.
I don't know about these algorithms, I jut wrote this algorithm when I neddeed it, It may be written in the past by someone, I am not sure. Please, provide the references of the algorithms you mentioned.

It is worth to mention in the help section, that you use the Knuth- or Fisher-Yates-Shuffle algorithm. There are several other implementations in the FEX using this method.

Thanks for your comment. Yes, you are right Darren.And here is the code:
r=a:b;
tmp=randperm(b-a+1);
r=r(tmp);

But my algorithm can be implemented in other programming languages where there is no randperm.

You can achieve the same behaviour with the function randperm too
