Description

I've been through the man page for trend1d backwards and forwards and I can't see a way to output the uncertainties of the estimated coefficients that are computed by trend1d.

For example, say you want to fit a linear function with trend1d, -N2r. How does one output the sigma of the slope, the sigma of the y-intercept and their correlation?

In looking at the code for trend1d, I see that the contents of temp_inverse_ij is never output. Maybe an option could be added to allow the user to dump the covariance matrix of estimated parameters?

I use GMT5, but this probably applies to all versions of GMT.
