cart2grid
Interpolate a set of Cartesian points onto a binary grid.
Syntax
[grid_data, order_index, reorder_index] = cart2grid(kgrid, cart_data)
Description
cart2grid interpolates the set of Cartesian points defined by cart_data onto a binary matrix defined by the k-Wave grid object kgrid using nearest neighbour interpolation. An error is returned if the Cartesian points are outside the computational domain defined by kgrid.
Inputs
kgrid |
k-Wave grid object returned by kWaveGrid |
cart_data |
1 x N, 2 x N, or 3 x N (for 1, 2, and 3 dimensions) array of Cartesian sensor points |
Outputs
grid_data |
binary grid with the same dimensions as kgrid |
order_index |
the order that the Cartesian points appear in grid_data according to MATLAB's standard column-wise linear matrix index ordering |
reorder_index |
the order that the binary points in grid_data (according to MATLAB's standard column-wise linear matrix index ordering) appear in the original Cartesian data |
