How can I row-normalize a symmetric matrix so each row sums to 1?

Dear MATLAB community,

I am working with the bucky (“W=bucky”) matrix, an NxN matrix where N=60. I would like to row-normalize this matrix so that each row sums up to 1. I am aware of the command norm (and there might be other commands), but I'd like to command this manually, so I can better understand the process behind the calculaton.

If anyone has a clue on how to write this command manually, it is kindly appreciated. Thank you in advance.

Best,

Rajendra

? I do not find anything named normw() ?

Sorry, that was a typo! Let me fix that. I meant the command norm.

The below does retain symmetry. I am not positive at the moment that it would work for matrix that have non-zero entries on the diagonal.

newW = W ./ sum(W,2);
