As to what Matlab code you need, I cannot tell from the details you have supplied.

I need matlab code for fitting and estimation of my parameters with coef of regression. thank you

But there are an infinite number of possibilities for P1 and P2.

I am wroking on a problem that requires me to use the nonlinear regression for estimation parameters. I have 3 parameters in my equation: x=a+b.exp(-ct) I have data x and t I need matlab code for fitting and estimation of my parameters with coef of regression. Thanks |
