Hi! I have a 3d matrix of 0's and 1's. I would like to plot it with scatter3 with 0's showing up black and 1's showing up white. Is that possible?
Thank you, Inês

scatter3(X,Y,Z,S,C)
The final argument there is a colour vector, of equal length to the X and Y vectors. If you don't care about the marker type you can pass in [] as the S argument.

So in that case you will have to create the X, Y and Z values first. The X, Y and Z vectors that scatter3 takes as its arguments represent the points that it will plot, so you need to create these vectors in such a way that they include every (x,y,z) triplet. You should be able to do this using
doc meshgrid
but a scatter plot doesn't really seem like a suitable way of displaying such regular data filling a grid. It is unlikely you will be able to interpret much off it.
