You will be provided with an array or matrix that contains various numbers, in addition to an evening variable, e, set to 1 or 0. If e==1, then you should return an evened version of the matrix, wherein all odd numbers have one added to them to make them even. For example,

• if M = 1:10,
• then the evened array is [2,2,4,4,6,6,8,8,10,10].

On the other hand, if e==0, then you should return the same matrix with only odd numbers, wherein one has been added to every even number. For example,

• if M = 1:10,
• then the odd array is [1,3,3,5,5,7,7,9,9,11].
