MATLAB: How to add 1 to all even numbers and add 3 to all odd numbers in a vector

evenoddvector

I have no idea how to do this.I already created a vector by typing: vec = round(-10 + 35* rand(1,30)); and next I am suppose to add 1 to all the even numbers and add 3 to all odd numbers. Thank you in advance for the help.

vec=vec+1+mod(vec,2)*2;

Here I have used one bitget function or without any function???

a=[3 4 5 6 8]; % Just an example 
data_odd=a.*bitget(a,1);
data_odd(data_odd==0)=[]
data_even=a.*~bitget(a,1);
data_even(data_even==0)=[]

MATLAB: Odd and even numbers

You simply have to go back to the definition of odd and even. An (integer) number is even if it is divisible by 2, odd otherwise. Divisible by 2 means that the remainder when divided by 2 is 0. That is easy to test, the function to get the remainder is rem (or you can use mod).

As with many things in matlab you do not need a loop, the functions work on vector / matrices

m = [1 2 3;4 5 6]
iseven = rem(m, 2) == 0
