Hi experts,
Appreciate you time in responding to this query.
I have three data colums x,y and z. I mad a customised curve fit using "fit" command as follows:
[ff, gof, opt] = fit([x,y],z,fittype,opts);
plot(ff,[x,y],z)
Up to this every thing is fine and I am able to find the required curve fit parameters.
Here comes the problem.
I have x, y, z and ff([x,y]) column vectors. How to get the mesh plot of the ff([x,y]), x and y, so that I can use origin pro to plot.
Thanks in advance..
