Hi, I want to know the number of * .inf files between two elements of a cellthe number of * .inf files between two elements of a cell
here is my example in this picture ,so I want to indicate a start date and an end date
after i want to have the number of files that exists between these two dates, taking into account all the files have the same dates
here is an example:
start_date=20190102
end_date=20190128
we need a program that verifies just the first six characters of each name or else, I'm lost

An effiicent method based on simple logical comparisons of numeric vectors (serial date numbers):
>> d1 = '20190102';
>> d2 = '20190128';
>> n1 = datenum(d1,'yyyymmdd')
n1 =
737427
>> n2 = datenum(d2,'yyyymmdd')
n2 =
737453
>> num = datenum(regexp(matchList,'^\d{8}','once','match'),'yyyymmdd')
num =
737427
737447
737448
737455
737456
>> idx = n1<=num & num<=n2
idx =
1
1
1
0
0
>> nnz(idx)
ans =
3

Yup, Stephen is right. My answer doesn't work for different months and years. I'll delete that answer so that others don't use it. The use of datetime is much better.
