How to increase value of some matrix numbers

Hi,

I have a matrix as following and want to increase the value of numbers (that are less than 9) by 1.

M= [12,16,3,5,1,11,13,22]

I applied the below logic:

M(M<9)= [B(i)+1]

This is what I got:

M =

12 16 17 17 17 11 13 22

But, I look for a response like this:

M =

12 16 4 6 2 11 13 22

I appreciate it if you could help me.

M= [12,16,3,5,1,11,13,22];
M(M<9)=M(M<9)+1;
