how to find columnnumber of a specific headername?

I have a dataset 69x821. I used this code:

[num, txt, raw] = xlsread('data_copy');

In txt are all the headers for the variables. I want to find the columnnumber for the header 'TRIG'. I looked manually and it is on columnnumber 814. How can I let Matlab find me this number?

[tf, idx] = ismember('TRIG', txt(1,:));

If it is found then tf will be true and txt{1,idx} will be the 'TRIG' that is looked for
