delete rows in 3d-matrix
显示 更早的评论
Hi all,
How can I delete a row in a 3d matrix? I want to delete the upper row in the matrices: stuff(:,:,1:3)
stuff(:,:,1(:,1))=[]
doesn't work..
"Unbalanced or unexpected parenthesis or bracket."
Does anyone know the answer? Thanks.
Cheers,
T

What exactly is "the upper row"?

Not sure what you mean. In 3D people talk about a "slice" or a "plane" not a row. You can't eliminate just row 1 of slices 1, 2, and 3 because then the array is no longer rectangular - it would have a notch or chunk out of it. But you can get rid of a whole slice at a time.

Normally slices are the last dimension, like Jan had. So I guess you're taking the left-most slice that lies in the (row, slice), or Y-Z plane, basically the left face of the data volume, at least according to how most people think of it.
