Question

How can I iterate over matrix and change values under condition.. for e.g:
I have matrix m with size 100×100 and Im doing:

m(m<10)=func(elemnt);

element should be the current element at iteration.. How do I access the current element??

Answer 1

Try simply
m(m<10)=func(m(m<10));

example:

m=[[1 2 3];[5 6 7];[8 9 10]]

m =
1    2    3
5    6    7
8    9   10

m(mod(m,3)==2) = m(mod(m,3)==2) * 5
m =
 1   10    3
25    6    7
40    9   10

The only constraint is that your custom function can handle vectors.
