ASORT sorts an array or cell array of alphanumeric strings numerically rather than in ascii dictionary order

strings are divided into three different categories, which are returned in separate cells

- numerically sorted strings that contain only one readable number
- ascii dictionary order sorted strings that contain more than one readable or invalid numbers
- ascii dictionary order sorted strings that contain no numbers

see
> help asort
for explanations and options

this sorter can be used, for instance, to sort files with numerical extensions, eg,

f.1
f.2
f.3
f.10
f.21

look at the accompanying published m-file for a few examples
