i want to fill matrix with some numbers

i have some numbers (50,90,60,73,55,96,47,63,555,46,756,968,453,452,500) i want to distribute this numbers randomly in a matrix(80000,5)

Do you mean that the entire matrix should be filled with those values, chosen at random, or you want a matrix of zeros, with only 15 spots chosen at random, with those values?

Try this:

SomeNumbers = [50,90,60,73,55,96,47,63,555,46,756,968,453,452,500];
idx = randi(15, 8000, 5);
RandMatrix = SomeNumbers(idx);

Check = RandMatrix(1:5, 1:5)                            % Sample Output (Delete Later)

producing (in this run):

Check =
   555    60   968   453    96
    90    73   968   452    55
   756   500    60   555    60
    55    96    73    47    60
   452    50   453    60    46

This corresponds to the first option in my comment/question above.

If you have the Statistics and Machine Learning Toolbox:

% Inputs
v = [50,90,60,73,55,96,47,63,555,46,756,968,453,452,500];
M = zeros(80000,5);

% Generate unique random indices
idx = randsample(numel(M),numel(v));

% Fill in the matrix. (Uses linear indexing)
M(idx) = v;

(This corresponds to the second option in my comment/question above.)
