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

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.
