算荧光衰减时间或者寿命的软件.matlab语言编写.

function TotalDecay = lifeFunc1com(params,Time,pp)


Amp1 = params(1); 
Life1 = params(2); 
iback = params(3);
Dback = params(4);
TimeShift = params(5); % shift in time variable

TimeWithShift = Time + TimeShift;

 InterpolateInstResp=pp(TimeWithShift);

InstRespForCalc = InterpolateInstResp +1+iback;
InstRespForCalc2 = InstRespForCalc(2:end);InstRespForCalc2(end:end+1) = 0;


Decay1 = filter(Amp1*0.5,[1;-exp(-Time(2,1)/Life1)],InstRespForCalc*exp(-Time(2,1)/Life1)+InstRespForCalc2);
TotalDecay = Decay1+Dback;
