Specify grid of cells and compute/plot values inside
显示 更早的评论
I have a scatter of (x,y) coordinates with an associated velocity value.
I need to specify a grid of cells of “n” vertical and “m” horizontal elements, compute the average velocity in each cell, plot the grid on the (x, y) plane colored by average cell velocity, and finally export the grid of velocity values.
I assume there is a straightforward way of grouping the (x,y,v) values in each (m,n) cell (I heard about binning although I am not familiar with the tools) and computing the average cell velocity.
Any thoughts and hints would be most welcome.
Thank you in advance.

Generally speaking:
You can discretize the coordinates independently, to get bin numbers along the x and y axes.
Or you can use the bin numbers as coordinates (first parameter) for accumarray with the corresponding velocities as the second parameter, and specify the function mean (watch out, function does not go in the third parameter.)
