Simulation of nonlinear systems with sparse input vectors using CRC technique

The cross referenced coordinate (CRC) method is introduced for computationally efficient analysis and simulation of nonlinear systems encountering a class of sparse vectors. In the CRC technique, the non-zero sections of the vector are used to form a matrix known as the CRC equivalent representation of the sparse vector. The system operators, including convolution, have been modified to operate with these equivalent matrices. A non-iterative algorithm is developed to provide the solution to nonlinear dynamic systems. In contrast to existing solutions, convergence of this algorithm is not an issue. A general purpose MATLAB toolbox is presented which is capable of CRC method based simulation of nonlinear systems.
