Code style

Functions are preferred to scripts.

Nested structs are used to hold data, so that the data is labeled explicitly rather than relying on an indexing convention.

Fields in structs can be dynamically accessed with the someStruct.(fieldName) syntax; i.e.,

fieldName = 'someField';
someStruct.(fieldName) == someStruct.someField;  % is true

and they can be iterated over in a loop like so:

fields = fieldnames(someStruct);
for i = 1:length(fields)
  % Note the cell-array indexing with braces rather than parentheses
  field = fields{i};
  doSomethingWith(someStruct.(field));
end

or, more concisely,

for field = fieldnames(someStruct)
  % This line is strange but necessary because MATLAB has awful semantics
  field = field{1};
  doSomethingWith(someStruct.(field))
end

The second construction is more readable, but doesn't work with parfor loops.
