find a value in a struct

Hi,

I have a struct of data (attached) and I want to find in it a value or better the index of the position of this value.

For example, I want to find the value 58 in clusters: it is in the first field clusters(1).cluster, so I want in output 1.

If I want the value '3', it is in the third field clusters(3).cluster so I want in output 3.

can you help me? thanks.

valuetofind = 58;
find(arrayfun(@(s) ismember(valuetofind, s.cluster), clusters))
