Comparing 2 matrix with not the same dimension

Lets say I have these 2 following matrix (which are not the same dimension):

A=[2 1 4 3 5 6] B=[5 4 3 1]

My goal is to find the following logical array:

A2=[1 0 0 0 0 1]

where 1 is the logical condition when a value in A is missing in B (again it must check the whole array B because dimension are not the same).

Thank you so much in advance for your answer !

Regards,

Pierre

Use the ismember function and the logical negation ‘~’ operator:

A=[2 1 4 3 5 6];
B=[5 4 3 1];

A2 = ~ismember(A,B)

A2 =

    1×6 logical array

     1   0   0   0   0   1
