Compute a positive definite estimate of the Ensemble Average Propagator (EAP) and Orientation Density Function (ODF) using the approach of Cjeng et. al (2012).

1 2	## S4 method for signature 'dtiData' dwiSqrtODF(object,what="sqrtODF",order=4,forder=1,lambda=0,D0=1.4e-3)

`object`	Object of class `"dtiData"`
`what`	Character, currently only "sqrtODF" is possible
`order`	Even integer, Order of spherical harmonics approximation.
`forder`	Integer, Order of radial approximation.
`lambda`	Non-negative, Regularization parameter.
`D0`	Numeric vector, grid of diffusivity parameters, typically about 1e-3.

signature(object = "ANY"): Returns a warning.
signature(object = "dtiData"): Compute a positive definite estimate of the Ensemble Average Propagator (EAP) and Orientation Density Function (ODF) using the approach of Cjeng et. al (2012).
