How to use use = logical operator on multiple values?

For example if I had vector A = [1,5,8,2,6,4,3];

And I want to check if A equal to 1st value, 2nd value or 4th value

istead of doing:

A1 = (A == A(1))| (A == A(2)) | (A == A(4))

Is there a shorter way, so like: A1 == A(1,2,4)

idk how to explain soz

Probably you could use ismember.

Koki, can you explain with a clear example. What does the statement "A equal to 1st value, 2nd value or 4th value" means? A is a vector, and its elements are scalar? How do you want to compare?

As suggested by stephen, you can simply use ismember

A1 = ismember(A,A([1 2 4]));
