% FDVDT103 - computes value of dV/dt for reduced, 2-variable HH model:
% dV/dt = {iext - Gna*minf(vv)^3*nvtohv(nv)*(V-Ena) - Gk*ninf^4*(V-Ek) - Gleak*(V-Eleak)}/C
% NOTE sethhparms must be called first to set up HH parameters.

% Parameters (mS/cm^2, mV, uFd/cm^2)
% hps = [gnamx=120; Ena=55; gkmx=36; Ek=-72; gleak=0.3; El=-49.4; C=1]
