Hi
I was reading on Matlab refrences :
A = 4×4
16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1
Replace all values less than 9 with the value 10.
A(A < 9) = 10
If I want to add 5 to the values that are less than 9 rather than repalce them with 10 how would I go about it please?
Thanks

Use the same selection on the right hand side of the equal sign
A(A<9) = A(A<9) + 5
I myself prefer to code it like this
tf = A < 9
A(tf) = A(tf) + 5
