I have a 2D pressure field and I would like to interpolate the value at particular set of singular points or locations. I'm suspect downscaling is a solution but before I try and write the functions for python, I was wondering if there is a way/code already in existence. Perhaps scipy has a function but I'm unaware and cannot find any.
Any help is appreciated
Scipy has a 2-dimensional interpolation function:
scipy.interpolate.interp2d
Information on how to use this function can be found on http://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.interpolate.interp2d.html
scipy.interpolate.interp2d(x, y, z)
in which x
and y
are 1-dimensional arrays of coordinates corresponding to the two dimensional array z
which is your pressurefield.
x
corresponds to the second axis of the z
-matrix. y
corresponds to the first axis of the z
-matrix
