Hi all
I am trying to do a curve fit following an example found on the net.
http://www.mathworks.co.uk/support/tech-notes/1500/1508.html
below is the code..Can someone explain the code below please.
especially A= params(1) and lamda=params(2) what are they doing (what is params?)
function sse=myfit(params,Input,Actual_Output)
A=params(1);
lamda=params(2);
Fitted_Curve=A.*exp(-lamda*Input);
Error_Vector=Fitted_Curve - Actual_Output;
it might be a stupid question but I just dont know

params seems to be an input to the function. The code is pulling out specific values of that input and naming them something more intuitive.
