pmatrix

plmatrix

function depending on a matrix argument, and providing a matrix valued 
 result.

see documentation for function <code>pvec</code>

&#8230;

number of threads to use. Defaults to number of threads specified for openMP,
 see documentation of package awsMethods.

mc.cores

parellelizes the execution of a function on matrix elements
 by splitting the matrix by columns and submitting each part to one core. 
 The function must take a matrix argument, with computations depending on
 row entries. It creates a matrix with same number of columns as on input,
 but possibly different number of rows.

Diffusion Weighted Imaging (DWI) is a Magnetic Resonance Imaging
modality, that measures diffusion of water in tissues like the human
brain. The package contains R-functions to process diffusion-weighted
data. The functionality includes diffusion tensor imaging (DTI),
diffusion kurtosis imaging (DKI), modeling for high angular resolution
diffusion weighted imaging (HARDI) using Q-ball-reconstruction and
tensor mixture models, several methods for structural adaptive
smoothing including POAS and msPOAS, and a streamline fiber tracking
for tensor and tensor mixture models.
The package provides functionality to manipulate and visualize results
in 2D and 3D.
