I have fixed integer like: 0,1,2,5,6,7,10,11,12. Now i want to generate a random matrix like: 6,0,1,5,7,10,12,11,2. is there any function??

I'm sorry but could you be clearer with what exactly you want out of your code? How is the second set related to the first set of numbers, if at all it has to be related? Do you need a random matrix or just a vector as you've typed out? I see you asked a similar question earlier as well.

a = 1:10
a = a(randperm(numel(a)))

From what I understand you would like to generate random numbers from your set:
>> fixed_int = [0,1,2,5,6,7,10,11,12]
One approach is as follows:
>> randperm(length(fixed_int))
This will randomly permute all the numbers in fixed_int. If you would like to generate them one by one then use the following:
>> randperm(length(fixed_int),1)
