Hallo all... I have a couple of plot values that I am trying to derive a formula from. The points are almost linear but not quite... Was hoping someone could shed some light on how to go about this... I have Matlab 7.1, would like to use it if at all possible.... Any help would be appreciated.
Welcome to PF; Turning a plot into an equation is called regression analysis. You have to start out with a good idea of what the underlying equation should be before you start. If you only have two points, then you can only plot a line - I'm guessing you mean you have a couple of datasets that, when you graph them, make something that looks like it's trying to be a line. The matlab function you want will be: polyfit ... you want to find the line y=mx+c that best fits the data.
