Hi All, I am curious about the slice function. After reading about the volumeteric slice plot on matlab https://www.mathworks.com/help/matlab/ref/slice.html it says the slice(...,'method') specifies the interpolation method. If I am using the the slice function on an array with X, Y, Z, and V data What does the slice function interpolate? Because The cell should have the value of V from the matrix at all cells and shouldn't have to interpolate?

Also, an example of Linear interpolation is (2 4 6 8) over 8 feet the value interpolated at 7 feet is 7?

You can define a slice to be at an arbitrary angle which will cut through your 3d volume at sub-voxel locations so interpolation would be done in V to get an estimate of these locations, as in the very top diagram on the page you linked and the second example which uses a non-axis-aligned plane.
