I have a function I want to evaluate by replacing its arguments with rule, however the result differs from when I manually enter the arguments,e.g., Given a functon test[x_, y_, z_]:= Total@Log[DeleteCases[Chop[{x, y, z, 1 – x – y – z}], 0]] Evaluation through applying rule yields undesirable answer: In[2]:= test[x, y, z] /. {xRead more
