MATLAB: Is it possible to obtain a random sample of values from a matrix without the randsample tool

MATLABrandom sample

Is it possible to obtain a random sample of values from a matrix without the randsample tool?

A=magic(6);
out=A(randi(numel(A),1))

if you want 3 values for example

 out=A(randi(numel(A),3,1))

Use randperm to compute a random permutation of indices into your value instead of a random permutation of your values:

values = [1 3 4 5]
randidx = randperm(numel(values));
randvalues = values(randidx)
%or as one line:
randvalues = values(randperm(numel(values)))

Can you please explain the evidence that makes you say that "the random sampling seems to be incorrect"?

When I run the commands

figure
hist(sample1,values)
figure
hist(sample2,values)

the results look as I would expect.
