Using sscanf to extract numbers from string
显示 更早的评论
Hi everyone, I'm having some trouble with sscanf, I'm trying to read two sets of number from a string which looks something like this 30cycles_sample2_11_29.csv. I want to extract the last two numbers, separated by underscores. Since the format of the string won't change I'd like to just read all numbers from the string, and can separate out the ones I'd like after. I've tried sscanf('30cycles_sample2_11_29.csv','%f') and variations but can only ever read the first number, 30 in this case. Any help is appreciated!

This works for me:
str = '30cycles_sample2_11_29.csv';
out = sscanf(str, '30cycles_sample2_%2d_%2d.csv')
out =
11
29

My pleasure!
You can also just use ‘%d’ and leave out the field width:
out = sscanf(str, '30cycles_sample2_%d_%d.csv')

%f instead of %d, i guess
