function an = alphn(V)% ALPHN(V) - HH alpha function for n variable. Note vectorized. an = zeros(size(V)); indx = find(abs(V+50)<0.001); if isempty(indx)==0 an(indx) = 1./(10-(V(indx)+50)/2); indx = find(abs(V+50)>=0.001); if isempty(indx)==0 an(indx) = 0.01*(V(indx)+50)./(1-exp(-(V(indx)+50)/10)); end else an = 0.01*(V+50)./(1-exp(-(V+50)/10)); end return% if abs(V+50) > 0.001% an = 0.01*(V+50)/(1-exp(-(V+50)/10));% else% an = 1/(10-(V+50)/2);% end%return?? 快捷鍵說明
