This manual documents the use of Fuzzy Logic Tools (FLT), a C++ framework for storage, analysis and design of fully general multiple-input multiple-output (MIMO) Takagi-Sugeno fuzzy control systems, without constraints in the order of either the inputs or the output vectors.

This reference manual is intended as a reference work for those developers wishing to use the tools provided by the FLT. Therefore, the text is structured following the typical pattern of reference manuals. Firstly, a general description of the variables, functions, classes, methods and attributes included in the software is presented. Then each of these items is studied in depth. Finally, some examples of using the FLT are included. These functions can be used for the analysis and design of TS-type fuzzy control.
