摘要

This paper presents a heuristic algorithm for generating asymmetrical practical test functions using MATLAB procedures. Based on the fact that differential equations can generate only functions similar to test functions (defined as practical test functions), the invariance general properties suitable for generating symmetrical pulses as related to the middle of the working interval are presented. Then some possibilities for obtaining asymmetrical pulses as related to this middle of the working interval using the derivative of such symmetrical pulse are studied, for certain differential equations corresponding to second order systems (with unity-step input and for an input represented by a gaus-sian pulse). Finally it is shown that we can obtain an oscillating system by joining such working intervals and restoring the initial null conditions for a second order system, in an adequate manner.
