Hi folks,
I wanna obtain the slope of the trend lines which have been calculated for time series. As you can see in the attached plot, there are 3 time serie and trend line has been shown for each one. How can I obtain the slope of each trend line?

polyfit is not applicable on time series because the x values are dates.
Error using polyval (line 67)
Inputs must be floats, namely single or double.
