利用Matlab模拟细胞HH 模型中的所有参数变化和动态Action Potential 生成过程

function iec = iexthh(t)

% iec = iexthh(t)
% IEXTHH(t) returns the current at time t, for HH simulation. For a
% square wave current, current has amplitude IEXHH uA/cm^2, and is on
% during [TSTHH, TNDHH]. IEXHH, TSTHH, and TNDHH specified as globals.

	if t>=TSTHH & t<=TNDHH
		iec = IEXHH;
	else
		iec = 0;
