MATLAB: Re-generate random matrix

distribute a matrix randomly

I have a matrix A (9X9) and I want to generate a new matrix B using the same matrix of A and should be distributed randomly and each number should be used once to generate matrix B.

Best Answer

ind=randperm(81)
B=reshape(A(ind),9,9)

MATLAB: Is there a way to re-generate MATLAB code form Packaged MATLAB App

If you are using https://www.mathworks.com/help/matlab/creating_guis/app-creation.html "Package App" from the toolstrip, then the entire code will be included in the package.

If you use MATLAB Compiler, then it is not easy to get the source back, but it is possible to explore the way the program is structured using the debugger.

MATLAB: Random

x   = [1     2     3     4     5
6     7     8     9    10
11    12    13    14    15
16    17    18    19    20];

EDIT after Mohammad's coment

[m,n] = size(x);
df = bsxfun(@plus,fullfact(m*ones(1,n)),(0:n-1)*m);
k = randperm(size(df,1));
out = x(df(k(1:min(100,numel(k))),:));

[m,n] = size(x);
xc = mat2cell(x,m,ones(n,1));
cc = cell(1,n);
[cc{:}] = ndgrid(xc{:});
k = randperm(numel(cc{1}));
out =  cell2mat(cellfun(@(x)x(k(1:min(100,numel(k)))'),cc,'un',0));
