A = PARSE_NUMBERS(S) separates the string, S, into a cell array of substrings which are individually scanned to determine numeric values; results are returned in matrix A.

The behavior of PARSE_NUMBERS can be modified by additional options which are specified as propertyName/propertyValue string pairs; lists of values can be specified as cell arrays of strings.

Options:
NAME / VALUE
-------------------
'del' --delimeter strings
'key' --identifier strings
'dec' --alternative decimal strings
'fmt' --format string passed to sscanf

-----
Please note: There are many ways to achieve similar results by applying one or more of the built-in Matlab string handling functions directly.
