Changing numbers in a matrix with new numbers

I have a matrix A:

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:

B=

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];

I have a vector [2 2.2 2.3 2.4] and if I put it like that instead of being

A

0 0 2 0 2.2

2.3 0 0 2.4

It shows

0 0 2.2 0 2.3

2 0 0 0 2.4

how can I put it in that order?

[Walter Roberson]

A = A.';
A(logical(A)) = [2 2.2 2.3 2.4];
A = A.';

MATLAB always goes down columns when assigning multiple values, not across rows.
