Dear Ferreters
G'day
I am attaching an image in which there are four terms that I am trying to compute.
term-1 = d(theta)/d(time) on z depth
term-2 = d(theta)/d(time) on n depth
term-3 = d(z)/d(time) on n depth
term-4 = d(theta)/d(z)
In my understanding...
term-1 is the differentiation of theta w.r.t. time and can be calculated as theta[l=@ddc]. However, here I am having confusion that whether the term-1 is a differentiation or linear trend.
or shall I compute the derivatives w.r.t. time and then compute the slope?
In ferret, differentiation are having operators like @ddc and the slope is from go regress. @ddc considers all the points but the slope depends on the final and initial terms.
Cheers, Saurabh
