| Hello All, I want to perform a fit to a data set in order to obtain the model parameters which best fits the data. Moreover I added a value (coming from the experiment) for each of the parameters as a fit constraint. Until here nothing special, but... |
| Hi All, I want to do a ListPlot in a logarithmic scale with error bars. Specifically I want to plot some points with the corresponding error bars. I have no been able to find the mathematica command that allows to plot the points with the error bars... |
| Hi all, I am trying to solve the following system of two equations in order two obtain a value for the two parameters I am interested in. The two equations are the Real and the Imaginary part of the same function which I called pol, and both of the... |
| Hi all, I have to solve the following system of equations. [mcode]F1[s_]=NIntegrate[F1[sp]*T1[sp]/(sp-s-I*10^-6),{sp,0.6,Infinity}]+NIntegrate[F2[sp]*T2[sp]/(sp-s-I*10^-6),{sp,1.1,Infinity}];... |
| I have two different data sets to be fitted with two different models with the NonlinearModelFit, that is model1 will fit data1 and model2 will fit data2. The data takes also into account the error of the measurement. Both models share the same... |
