comment Referring to the components of a vector within a sum
@Ben -- I think the point is that it is often better (when programing in Mathematica) to not express formulas in an index-by-index fashion, but rather to use operations on the vectors/lists.

comment Plot gives different result than direct evaluation (Plot[f[x]] obtains answer while f[x] fails)
Are you sure that you are not being fooled in the Plot by the automatic scaling? Try PlotRange->All and make sure you still like the values you see.

comment FindMaximum slow for fixed parameters
Maybe you could find a simpler problem (with code that can be run) that shows the same behavior? It's almost impossible to figure out what's happening when we have no idea what the functions are.

comment How to find out where an error occurs?
Break your code into cells and evaluate a few lines at a time. When they all work, consolidate them.
