MATLAB: Changing numbers in a matrix with new numbers

findmatrixmatrix manipulation

I have a matrix A:

0 0 1 0 0

1 0 0 0 1

0 0 1 0 1

Then with some functions I find the coordinates of the 1 in the matrix and apply a code, after that those ones wont be ones anymore, will be a different number. How can I put the new numbers in the matrix, changing the ones with the new numbers?

In other words, I would like something like this:

0 0 7 0 0

6 0 0 0 7.6

0 0 8 0 8.1

I am going to put my code for easier understanding. Thank you!

A(logical(A)) = [6 7 8 8.6 8.1];
