I have a 3D matrix, .mat file attached in this thread, which has a 200x200x600 matrix has 5021 non-zero values and 23.9 million zero values.
It is a cuboid grid (x and y = -200:200 and z = -600 to 600) that contains charge data.I used the vol3d v2 function to visualize the 3D cuboid grid that I have, however the number of zero values dilute the non-zero values making it unable to observe the grid properly.
I believe obtaining a slice of the grid at x=y=0 would provide some insights as how the charge is distributed (this is a charge grid), however I am unable to create a meshgrid for the co-ordinate axes where x=y=-200:200 and z=-600:600
The in-built MATLAB app – volumeViewer yeilds a similar result. Hope you could provide some direction, I have attached the .mat file containing the 200x200x600 matrix if it is any help.
