I have directory names that end in ‘0.0100’. I want to be able to skip certain directories by comparing the substring ‘0.0100’ to the directory name. How can I do this?

You can use the ‘contains’ function to determine whether a string contains a given substring or not. Specifically, ‘contains’ returns true if the first argument contains the second argument and false otherwise. For example:

>> smallSubstring = '0.0100';
>> largeString1 = 'Item0.0100';
>> largeString2 = 'Item0.0101';
>> contains(largeString1, smallSubstring)
ans =  logical   1
