How to check a number is in a array or not?

a=[8 9 6 5 3], I want to know 5 is there or not.

Answer 1

[Guillaume]

Use ismember:

ismember(5, a)

[Putri Basenda Tarigan]

Excuse me Sir,

For the same problem, if we don't know that the number is 5, how to code to get that the number is 5?

[Matthew Coile]

Putri, you can just as easily use a variable. That is, ismember(x,a) would work as well, where the value of x is assigned earlier in the script.

Answer 2

[José-Luis]

 sum(a==5) > 0

 any(a==5)
