How to loop through structure with words?

Hi guys,

I would like to systematically change the name in the loop (from BreakingGlass to WhiteNoise) to work in the 6X9 matrix.

My Idea is to do:

reflectance.nhy1.NAME OF SOUND.(:,:)

I need to do

tones = '1'; The 1 is just an example which works, but I need to do this with

tones = 'BreakingGlass', but then the str2num function gives me a NaN back, how can I solve this problem?

finish_tones = str2num(tones)

How can I fill a new name of sound in each iteration?

Thank you for your help!

[Fangjun Jiang]

fn=fieldnames(reflectance.nhy1);
for k=1:length(fn)
    reflectance.nhy1.(fn{k})
end

Thank you, now it works
