create 3d grid and quantize the 3D points

Hi everyone,

I have 3D points. Now I want to create a 3D cells/grid and quantize the points into that grid/cells. In case of 2D, lets assume, there is an image of size 6x6, and we create grid of 2 x 3, and all image points will be in those 2 x 3 grid. I want to make sure all ponits in original image should be quantized into 6 numbers. As shown in the Figure below;

@Aravin,

Please provide an example of the 3D array you want to quantize into a grid. It is possible that interp2() will be useful for you. Provide the data you want to quantize. Thank you.

Consider 2D example. There is an image with x,y coordinates. I want to create a grid of 2 x 3 and I want to make sure all ponits in original image should be quantized into 6 numbers. As shown in the Figure below;
