Making all Elements in Matrix Even.

I want o make all the elements in the Matrix even.

For eg.

if the matrix is a=[53, 59, 61, 87],

The output matrix b should be b=[54, 60, 62, 88].

I have tried this,

for l=1:length(a)
    if mod(l,2)==1
        l=l+1;
    end
    b=(:,l);
end

but it doesnt work.

Any help would be appreciated.

Thanks.

a=[53, 59; 61, 87]

a = 2×2

53 59 61 87

b = a;
for l=1:numel(b)
    if mod(b(l),2)==1
        b(l)=b(l)+1;
    end
end

b

b = 2×2

54 60 62 88

a=[53, 59, 61, 87] ;
iwant = a+mod(a,2)

iwant = 1×4

54 60 62 88
