Hi,
I am trying to compare vector A to vectors B, C, and D. If an element from vector A does not appear in vectors B, C, and D I would like to print it out.
For Example:
A = [15.00; 20.00; 7.50; 8.75; 30.00; 125.00; 12.25]
B = [35.00; 25.00; 15.00; 15.00; 20.00; 7.50; 30.00; 125.00; 12.25]
C = [0.00; 5.00; 0.00; 0.00; 10.00; 0.00; 0.00; 0.00; 0.00]
D = [35.00; 30.00; 15.00; 15.00; 30.00; 7.50; 30.00; 125.00; 12.25]
I would like to print out that 8.75 was missing from vectors B, C, and D.
Thank you

This should do it:
out = A(ismember(A,[B;C;D]) == 0)
You can then output the out values however you want. Note, I assume you meant if it doesn't appear in any of the three vectors (as written). You'd have to change the condition slightly if you meant all of them at the same time.
