setReshapeVecMat
Defines functions to reshape a vector into a matrix and vice versa.
Contents
Syntax
seti = setReshapeVecMat(seti)
Description
seti = setReshapeVecMat(seti) defines functions seti.GROI and seti.GCD to reshape vectors into matrices of size seti.nROI
- seti.GROI to reshape a vector into a matrix of size
Example
init; seti.dim = 2; seti.nCD = 8; seti.nROI = 3; seti = setReshapeVecMat(seti);
v = rand(seti.nROI^seti.dim,1) % vector M = seti.GROI(v) % write vector as matrix v = seti.iG(M) % write matrix as vector again
Input Arguments
- seti.dim : see setGrid.html.
- seti.nCD : see setGrid.html.
- seti.nROI : see setGrid.html.
Output Arguments
- seti.GROI : reshapes a vector of size seti.nROI^seti.dim into a matrix of size seti.nROI x seti.nROI in 2D and seti.nROI x seti.nROI x seti.nROI in 3D.
- seti.GCD : reshapes a vector of size seti.nCD^seti.dim into a matrix of size seti.nCD x seti.nCD in 2D and seti.nCD x seti.nCD x seti.nCD in 3D.
- seti.G : same as seti.GROI.
- seti.iG : reshapes a matrix into a vector.
