Issue #88: Fixed multiple function concatenation bug #89

Closed alexandrustana closed 4 years ago

alexandrustana commented 7 years ago

Possible fix for the concatenating function bug.

In order to check that the following case does not appear sincos(x) a check is added in the ShuntingYard which verifies if 2 function tokens are detected and between them is no other token. This verification will ensure that only sin(cos(x)) is valid.
