MATLAB: Random distribution row number

random distribution

I have matrix A with 1×10 elements and B with 1×125 elements. But elements in B are those elements in A only but randomly distributed. Now I want to get the row number of each element in B corresponding to matrix A.. can anybody help me .. thanks in advance

Best Answer

[idxB, idxA] = ismember(B, A);

idxA is index of A members in B.

   A = randn(10,10);
   B = A(3:6,:);
   [C,IA,IB] = intersect(A,B,'rows','stable');

IA gives you the row indices in A where B is

MATLAB: Random Gaussian variable distribution

If you want normally-distributed random numbers with zero mean and unit variance (and therefore unit standard deviation), use the randn function:

N01 = randn(1,10);

This will generate a 10-element row vector with zero mean and unit variance.
