I am having 'n' randomnly generated positive decimal number. With this input I have performed some set of mathematical calculations. Now i need to repeat the mathematical calculations with changed order of decimal number and this has to be followed for each iteration until a certain condition is met.
Example:
A= 5, 2, 4, 3, 7, 1, 6
Expected output: Shuffle decimal number for each iteration. [only positive number is required]

Hello Dyuman joshi. The code you have suggested works very well, when it is applied seperately. But while i use this same code and apply some calculation after randperm(n), I didn't get different decimal numbers for each iteration. Can you please guide me where I am making mistake. Thank you.

Can you show your code? Without the code, it is difficult to tell where the problem is.

It seems you try to do something like a minmum search. Probably, you can solve the origin problem in a more target oriented way.
For your question to shuffle a vector you could do something like this:
Expect having a vector with several digits. In this example 1 to 7:
vector = 1:7;
For example, you could shuffle it like this:
vector = vector(randperm(length(vector)));
