Matlabs scatteredInterpolant for julia?

[Markus F.]

Hi,

i use matlab at the moment, but want to chance to julia (opensource...).

In one of my programms i have to grid and interpolate scattered data (x,y-coordinates and internisity data of an image) to a regular grid.

In matlab my code looks like:

[x,y]=meshgrid(xmin:stepy:xmax,ymin:stepy:ymax);

 F=scatteredInterpolant(pc.xdata, pc.ydata, pc.idata,'natural');

interp_image=F(x,y);

Is there any nice and easy way to do that in julia?

thanks and best regards,

Markus

The https://github.com/kbarbary/Dierckx.jl package can interpolate from unstructured sets of points.
