isprime (MATLAB Functions)

Detect prime elements of array

Syntax

```
TF = isprime(A)
```

Description

TF = isprime(A) returns an array the same size as A containing logical true (1) for the elements of A which are prime, and logical false (0) otherwise. A must contain only positive integers.

c = [2 3 0 6 10]

c =
     2     3     0     6    10
