mvpa2.misc.plot.flat_surf.unstructured_xy2grid_xy_vectors(x, y, min_nsteps)

From unstructured x and y values, return lists of x and y coordinates to form a grid

Parameters:

x: np.ndarray :

x coordinates

y: np.ndarray :

y coordinates

min_nsteps: int :

minimal length of output

Returns:

(xi, yi): tuple of np.ndarray :

xi contains values ranging from (approximately) min(x) to max(x); yi is similar. min(len(xi),len(yi))=min_steps.
