Finding a sting - function strfind, MATLAB in Engineering

Assignment Help:

Finding a sting - function strfind:

The function strfind does necessarily similar thing, except that the order of the arguments does make dissimilarity. The common form is strfind(string, substring); it finds all the occurrences of the substring within the string, and it returns the subscripts.

>> strfind('abcdeabcde','e')

ans =

5 10

For both the strfind and findstr, if there are no occurrences, then the empty vector is returned.

>> strfind('abcdeabcde','ef')

ans =

[]
