If I have an array A= [1,2] and matrix B= [3,4;8,6;1,2], How can I say that array A is present in B?

Try ismember() with the 'rows' option:
[~, matchingRows] = ismember(A, B, 'rows')

Emmanuel, try this:
A= [1,2]
B= [3,4;8,6;1,2; 4,5; 1,2]
[inA, inB] = ismember(B, A, 'rows')
matchingRows = find(inB)
