I've been using Mathematica for many years and one thing still puzzles me. Elements of the array defined by the variable 'a' can be obtained using a[[i,j]]=expression. However, the command Array creates arrays comprised of elements named in the form 'a[i,j]'. Note the single brackets. Everything I see in the Mathematica book about brackets says that these are functions. This seems inconsistant to me. Shouldn't they be listed as 'a[[i,j]]' until they are defined? What are the single brackets supposed to mean if not elements of the array 'a'? Thanks in advance, Joe Slater -- ________________________________________________________________ Dr. Joseph C.
