I have two character vectors. Let's call them Source and Pattern. For each entry in Pattern, I want to know if it is represented in Source. Here is an example:
----------
Pattern = 'trapmf' // 'trimf' // 'pimf' ;
Source = 'dsigmf' // 'trapmf' // 'pimf' // 'gaussmf' ;
print Pattern Source ;
do i = 1 to nrow( Pattern ) ;
Match = any( Pattern[i] = Source ) ;
print Match ;
end ;
----------
Then the expected results are: Match = 1,0, 1 as expected. But I have to use a loop, which I consider to be inelegant. How can I use SAS/IML matrix manipulation to create an "outer product" character match?
Use the ELEMENT function:
b = element(Pattern, Source);
print b;
BTW, that performs a case-sensitive comparison. If you want a case-insensitive comparison, use the UPCASE function.

Exactly what I wanted! Thank you very much!
