Expand the vector, optionally extending the border into the expanded region.
Expand the vector, optionally extending the border into the expanded region. This operation is a key part of the FFT. The new vector is of size "bigSize" element (0) of this is anchored at (0) in the larger vector. If "borderFill" is true, then the two edges of the vector are extended evenly in all directions, as though the bigger vector were actually a loop with opposite edges touching.

Shape of the vector.
Rotates the elements of a vector, wrapping around the left side to the right side.
Rotates the elements of a vector, wrapping around the left side to the right side.
The rotation is specified by "delta"; for example, delta=2 would cause the element at location (0) to be moved to location (2). Returns the rotated vector. This was added in support of the LowPassFunction kernel, and because Matrix has a similar method. Not currently tested. -RJC XXX

A symmetric, positive semidefinite, order-2 tensor in 2 dimensions. See the paper "An efficient method for tensor voting using steerable filters," Franken et al, 2006, for a description.
This is implemented as a vector for efficiency because the matrix representation is redundant. The matrix form of a symmetric tensor:
is represented as a length 3 vector:
