cor_mat

Converted a vectorized upper triangular correlation matrix back to its full
matrix form.

internal

Supports fMRI (functional magnetic resonance imaging)
analysis tasks including reading in 'CIFTI', 'GIFTI' and
'NIFTI' data, temporal filtering, nuisance regression, and
aCompCor (anatomical Components Correction) (Muschelli et al.
(2014) <doi:10.1016/j.neuroimage.2014.03.028>).
