Name	Description
c	Returns a matrix of Boolean values. An element in c is 1 if and only if the corresponding element of a is prime. Otherwise, the element is 0. If a is a string, each element in c corresponds to a character in a. If a is a matrix, c is a matrix of the same size as a. If a is a string, c is a matrix with as many elements as there are characters in a.

Examples

C = isprime([5, 7, 6, 789])

C = isprime('der')
