grid2cart

Return the Cartesian coordinates of the non-zero points of a binary grid

Syntax

[cart_data, order_index] = grid2cart(kgrid, grid_data)

Description

grid2cart returns the set of Cartesian coordinates corresponding to the non-zero elements in the binary matrix grid_data, in the coordinate framework defined in kgrid.

Inputs

kgrid

k-Wave grid structure returned by makeGrid

grid_data

binary grid with the same dimensions as the k-Wave grid structure kgrid

Outputs

cart_data

1 x N, 2 x N, or 3 x N (for 1, 2, and 3 dimensions) array of Cartesian sensor points

order_index

the order that the Cartesian points appear in grid_data according to MATLAB's standard column-wise linear matrix index ordering
