The ILNumerics namespace provides the main datatypes to be used inside the library. At this time those are the main generic array type ILArray<> and the derived types ILCell and ILLogicalArray. The former is a simple alias for ILArray<object>. ILLogicalArray is to be used for boolean operations. Also the namespace provides 2 complex datatypes: complex and fcomplex, which extends the system's base value types for numerical mathematics on complex floating point base. Those base value types may as well be used as inner (generic) types for all ILArray<>'s. Some operations of ILNumerics.Net return a complex Array even on real input arrays. Therefore you may want to make yourself familiar with those types also.
