Other result accompanying fitted data

Hi,

In this thread Monod kinetics and curve fitting - MATLAB Answers - MATLAB Central (mathworks.com), two differential equation are integrated and fitted to experimental data and all is okay. The first ode computed for:

S = Sv(:,1);

How best can I report the accompanying values obtained from the other ode to which there is no experimental data, i.e.,

S = Sv(:,2);

Thank you in advance.

I am pleased that you found my code helpful!

The code fits only one vector, so it only has one output. To get all the results, the easiest way would be to copy the differential equation function, and in the second version of it (with a slightly different name), set:

S = Sv;

and then run it with the fitted parameters. Use a different ‘tspan’ as well, with a higher resolution to get a smoother curve (use linspace to create it), if desired. Another option would be to save it and the fitted parameters to a .mat file.

Thanks Strider! You are a true champion.

As always, my pleasure!

My apologies for not seeing this yesterday. I was away for several hours and was not as careful as I usually am about perusing Answers when I returned. Thank you for bringing it to my attention.

I am having one other query about this problem. I have asked the question here: lsqcurvefit: Function value and YDATA sizes are not equal. - MATLAB Answers - MATLAB Central (mathworks.com). Again, your knowledgeable intervention is highly appreciated.
