Hello Scilab users! I have a problem with simple Xcos diagram. I'm trying to get Dirac delta function as a derivative of Step function.
Xcos diagram is in attachment ( dirac_problem.zcos <http://mailinglists.scilab.org/file/n4031722/dirac_problem.zcos> ). I use the following blocks: CLOCK_c ENDBLK (final simulation time is 2) CLINDUMMY_f STEP_FUNCTION (step time 1.0, initial value 0, final value 1) DERIV DIFF_f scifunc_block_m (with y1=diff(u1) function inside) CMSCOPE 3 TOWS_c for saving results to workspace (step, dirac1 and dirac3). If I manually do diff(step) I get expected Dirac function. If I replace STEP_FUNCTION with RAMP (slope 1, start time 1, initial value 0) I get expected results - plot of Heaviside function (see ramp.zcos <http://mailinglists.scilab.org/file/n4031722/ramp.zcos> ). Can anybody help me? What is the correct way to obtain Dirac delta function in XCos?
