1. I want to create the following matrix:
A=[1 2 3 A B C]
2. After that, based on the matrix A, I want to generate random matrix of this following matrix:
A1=[1 3 2 A C B]
A2=[2 1 3 B A C]
A2=[2 3 1 B C A]
Does any body can help me?

As Paulo pointed out, this most likely requires usage of cells, e.g.:
>> A = {1 2 3 'A' 'B' 'C'};
>> A1 = A(randperm(6))
A1 =
[3] 'A' [1] 'C' [2] 'B'
>> A2 = A(randperm(6))
A2 =
[3] [2] 'C' 'A' 'B' [1]
However, if the integers and chars are always 1 digit/characte, then you can maybe also use the following approach:
>> a = '123ABC';
>> a1 = a(randperm(6))
a1 =
13A2CB
>> a2 = a(randperm(6))
a2 =
31BAC2

Well, you could do something like
>> a = '123ABC';
>> l = size(a,2);
>> rp = randperm(l/2);
>> a1 = a([rp rp+l/2])
a1 =
321CBA

c'mon you just need to put the randperm inside the loop, so easy :)
