I am trying to write a script that will check if (as x increments)

burstcountdata{x}

exists, so that if it doesn't it can be created with

burstcountdata{x} = []

so it can then be referenced. The program has to be run repeatedly (because of how the data exists across multiple .mat files of the same name) so it cannot constantly be overwriting testarray{x} as [], it has to only write it if it doesnt exist.

Currently I have:

if exist(burstcountdata{x}, 'var') == 0

burstcountdata{x} = [];

end

but this makes matlab throw a fit because it's burstcountdata{x} instead of 'burstcountdata{x}', and I don't know how to make x be treated as a variable within 'burstcountdata{x}'
