how to distribute a matrix elements randomly matlab

hi everyone how to make a matrix randomly distributed to another matrix n,

m = [ 1 1 3 3 3 4 4 6 6 7 7 7];

n = zeros(3,10);

the same value must in the sequence, ex : 4 4 4, 7 7 7.result reqiured can be something like {or other combinations):

distributed_matrix =

 0     1     1     0     7     7     7     0     0     0
 0     0     3     3     3     4     4     0     0     0
 6     6     6     0     0     0     0     0     0     0

Seems like an unusual, quirky thing to want to do. Is this homework? Hint: try unique() and randi(). Note, though it's solvable for that specific m and n, it may not be possible to solve for an n of that size (3x10) and any arbitrary m.

yes, this is one of thesis code :). i've tried unique and randi, but still don't know to distribute on another matrix would you like give me a solution?thank you before..

So Image Analyst.. please do his thesis work! Come on!

You should post what you have attempted so far, if it is homework; even if the results are wrong - to show that you at least tried.

m = [ 1 1 3 3 3 4 4 6 6 7 7 7]; n = zeros(3,10); x = randsample( numel(n), numel(m) ); n(id) = x; i tried this

Joking aside, try to subdivide the whole thing into sub-tasks. I try to give you an example:

1. Identify in vector m the k starting indeces of all repeated sequences of numbers.
2. Get k random indeces that fit the shape of matrix n.
3. Put the sequences in the matrix (after simple checking of their length and the row size)

Working on this maight help, I think.

thank you so much, I'll try ...
