How can I use an ode45 solution in matlab curve fitting toolbox?

I'm a bit new to Matlab and am unsure how to use my code output in the curve fitting toolbox. I have code that uses lsqcurvefit and an ode45 solver to best fit a solution to a differential equation to data while finding the best parameters. I know how to plot the solution give by ode45, but I'm unsure of how to save or hold this solution in such a way that I can use it in Matlab Curve Fitting Toolbox.

You can couple the curve fitting toolbox and ode45 in the same way as you did it for lsqcurvefit and ode45, namely by defining the model function as a function (from which you can then call ode45).

The output of the isqcurvefit can be stored in the variables. You can use these variables in the Curve Fitting Toolbox. It would be better for understanding if you share the code so the exact problem can be resolved.
