I am trying to generate rows of a determinant for a Hill's DE. To do this I generate a series of exponentials of the typical form a Exp[I t(-4 + x) - I t x] where the coefficient a and integer 4 vary from term to term. There also may be more terms in the exponent. Mathematica resolutely refuses to simplify the exponents, which in the above case would result in a Exp[-4 I t]. There are several terms which have different extended exponents but the same simplified exponents. To generate the determinant I need to collect all of the terms having the same simplified exponent. Any advice gratefully received. Wes
