RF = remapf(F, X, Y) remap the vector/scalar field(s) F to a new
grid defined by the vectors X and Y (expressed in the same units as the
original axis, usually in millimeters).
For instance, suppose you have a field F defined on a 64x64 grid, with
X ranging from 20 to 120 mm and Y from 20 to 100 mm. If you want to
remap your data onto a larger grid of 128x128 points, with X from 0 to
150 and Y from 0 to 100, do the following:
RF = remapf(F, linspace(0,150,128), linspace(0,100, 128));
Careful: you have to provide appropriate values if you want to conserve
the aspect ratio of the original field.
If the new grid is larger than the old grid, the remapped field is
filled with zeros.
The remap is based on Matlab's built-in function GRIDDATA.
If no output argument, the result is displayed by showf.
