Checks which elements of one matrix are member of an other matrix
tf = nan_ismember (A, S) [tf,S_idx] = nan_ismember (A, S) [tf,S_idx] = nan_ismember (A, S,'rows')
Return a matrix tf with the same shape as A which has a 1 if A(i,j) is in S and 0 if it is not. If a second output argument is requested, the index into S of each of the matching elements is also returned.
With the optional third argument "rows", and matrices A and S with the same number of columns, compare rows in A with the rows in S.
a = [3, 10, 1]; s = [0:9]; [tf, s_idx] = nan_ismember (a, s); tf = T F T s_idx = 4, 0, 2. a = [1:3; 5:7; 4:6]; s = [0:2; 1:3; 2:4; 3:5; 4:6]; [tf, s_idx] = nan_ismember(a, s, 'rows'); tf = [T; F; T] s_idx = [2; 0; 5];
