lsqnonlin -not enough input arguments-
显示 更早的评论
Hi all!
I need some help with lsqnonlin. The function is:
function [y] = FUN(p,t)
k1 = p(1);
k2 = p(2);
y=(exp(-k1*t)-exp(-k2*t))*((k1*k2)/(k2-k1));
And:
[p_stima] = lsqnonlin(@FUN,[0.4 0.5],[]);
The error is:
Not enough input arguments.
Error in FUN (line 4)
y=(exp(-k1*t)-exp(-k2*t))*((k1*k2)/(k2-k1));
Error in lsqnonlin (line 196)
initVals.F = feval(funfcn{3},xCurrent,varargin{:});
Error in plotHistFit (line 88)
[p_stima] = lsqnonlin(@FUN,[0.4 0.5],[]);
Caused by:
Failure in initial objective function evaluation. LSQNONLIN cannot continue
Thank you in advance.
Best regards

Your FUN function must only have one argument, namely p.

Therefore, the following modification could solve the issue,
t=???;
[p_stima] = lsqnonlin(@(p) FUN(p,t) , [0.4 0.5],[]);
