I just finished and released the initial version of rlc, a Common Lisp RLC circuit solver.
I've been toying around with Laplace transformations and testing the results with gnucap. To assist verifying the analytic solution with the gnucap simulation, I wrote a Common Lisp program to plot the output of the various solution formulas.
While I considered porting my C++ plotter library from CTSim to CLIM, I found that invoking xgraph from Lisp worked so well for this application that I couldn't justify the effort of the port.
