Write a function to determine which elements of an array are even numbers (i.e., …, -4, -2, 0, 2, 4, …). Your function should return a logical array of the same size as the input with 1s (TRUE) in the locations corresponding to even numbers.

How could I solve this?

Answer 1

[Konstantinos Sofos]

funvtion Out = findeven(In)

Out = ~mod(In,2)

end

Assuming:

In =

      -6    -5    -2     0
       1     2     3     4
       5     6     7     8
       9    10    11    12

Out =

       1     0     1     1
       0     1     0     1
       0     1     0     1
       0     1     0     1

[Meesha Lini Eesan]

A = [-10,-9,-8,-7,-6,-5,-4,-3,-2,1,0,1,2,3,4,5,6,7,8,9,10] % I assign -10 to 10 vector A. B = ~mod(A,2) %I used this function to find the even element using the ~mod function %(modulus) and output to True(1) and False(0)because I use only mod the %output will true(1) will be an odd number.
