Hi, I have a set of x and y values gathered from an experiment. I am to fit an underlying equation to this data and I am looking for MATLAB to find the coefficients, from this equation, for the line of best fit.
The equation the line of best fit is,
y= a*exp(-x/b) + c*exp(-x/d) + e*exp(-x/f)
Anyone know how to do this?
