Most functions can act on real or complex matrices (or the latter's real/imaginary parts separately). Much of the actual complexity of using Eigen in its native C++ environment has been hidden for AutoIt users, through extensive bounds and error checks, an intuitive function-naming convention, a large help file, and detailed tutorials and test examples. This library allows you to perform fast matrix operations on large numerical data sets, using special matrix variables and simple AutoIt wrapper functions. These wrappers call C++ wrappers in the dlls (also written by RTFC, source included). The dlls in turn re-map AutoIt memory and call one or more Eigen functions. All operations are memory pointer-based and act directly on the matrices created in your AutoIt script, obviating the need for data transfers. Both 32-bit and 64-bit environments are supported; in x64, matrices can be any size that fits into virtual memory.
