Ep03: generating file names for csv files and figures with sprintf

[shwina]

Can you provide a quick preview of what the code would look like with dir? Does dir have the same behaviour on all platforms?

The file name generation bit would look like this, and the rest of the script would be unchanged.

file_list = dir('*.csv');
for i = 1:length(file_list)
	data_file = file_list(i).name;
	img_file = replace(data_file, '.csv', '.png');
	img_file = replace(img_file, 'inflammation', 'patient_data');
end

I'd need to check that dir doesn't do anything different on Mac or Windows.

I think that looks fantastic, but remember that file_list here is a Cell Array (is that right?) that we haven't introduced. The dot operator is also new.

I'm completely in favour of introducing Cell Arrays before this section though.

Cool! file_list is a structure array, which of course will need explaining. I'll put something together and submit a PR for discussion.
