This paper describes the basic nature of the InducedNorm Control Toolbox (INCT). The toolbox is a set of Matlab-filesusing LMITOOL and the Semidefinite Programming package(SP). Thetoolbox is public domain. The INCT provides a series of analysisand synthesis tools for continuous time-invariant linear systems,all related to induced norms. A packing system has also beendeveloped to make the writing of code less cumbersome.
