Hello all Can any one explain me how can I use griddata in matplotlib for 2-d interpolation of polar to cartesian co-ordinates. I have two 1D arrays r and theta of 128 and 64 cells respectively I have a 2D array temperature T(r,theta) with (128, 64) cells. I would like to have Tnew(200,200) cells in cartesian coordinates x = r*cos(th) and y = r*sin(th)
for the same I use Tnew = griddata(x,y,T,xi,yi) .... and x = outer(r,cos(th)) and y=outer(r,sin(th)) where xi,yi = mgrid[x.min():x.max():200j,y.min():y.max():200j] I get a ValueError suggesting that griddata does not like to have 2D arrays of x and y How can I get this to work?
