Sure, how about this:
Given a set of x coordinates /x_1,...,x_m/ and a set of y
coordinates /y_1,...,y_n///, each in increasing order,
That should replace the following on the "2D introduction to
interpolation" page
(https://www.gnu.org/software/gsl/manual/html_node/2D-Introduction-to-Interpolation.html):
Given two sets of equally spaced grid points: /x_1,...,x_m/ with
spacing /\delta x/, and /y_1,...,y_n/ with spacing /\delta y/,
The rest of the description ("...plus a set of function values....")
can stay as is.

Hi David,
Do you think you could write a new sentence or two to describe more
accurately what the manual should say? I'm still a little confused
:-) I
can then just paste the new text into that section.
