MATLAB: Create a matrix from a vector

if statementiterationMATLABmatricesmatrix

Given the matrix M
M  =  [6  15 11 2 4  7  3 1 13;
       14 0  16 0 5  9  0 0 0;
       0  0  17 0 8  12 0 0 0;
       0  0  18 0 10 0  0 0 0;
       0  0  19 0 0  0  0 0 0;
       0  0  20 0 0  0  0 0 0]
and the vector V= [1 2 3 4 8 11 13 14 15 16 18 19];
I want to reconstruct the Matrix M with just the value in V, obtaing A
  A =  [0  15 11 2 4  0  3 1 13;
        14  0 16 0 0  0  0 0 0;
        0   0 0  0 8  0  0 0 0;
        0   0 18 0 0  0  0 0 0;
        0   0 19 0 0  0  0 0 0;
        0   0 0  0 0  0  0 0 0];
May someone help me?

Best Answer

A = ismember(M,V) .* M % Note: 14 should be in 1,1 not 2,1
