Hi Guys,
I used the basic fittings in the plot function to add a line of best fit, which MATLAB shows on the graph. I know want to use that equation in my code. Is there a better way than just copying it down as it it a very long equation.
Thanks
Jamie

Use these icons to export the fit model into workspace as shown in the Screenshot shown here.
Then use the exported fit model (e.g.: called fit) coefficients, e.g.:
x = 0:13;
FModel = fit.coeff;
FM_vals = polyval(FModel, x);
...
