Parameter Estimation for Differential Equation according to data measured

[mzarrabi]

Hello everyone,

I have a set of experimental data and a differential equation with two coefficients inside it.

I am trying to find these two coefficients using regression and by solving the equation.

Thanks in advance.

Here is a way how to do it:

Using the values for a and b you give as solutions makes the solve block fail (does not converge)!?
