scale_design_mat

Scale the columns of a matrix by dividing each column by its
highest-magnitude value, and then subtracting its mean.

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>).

scale_design_mat function

<dl><dt>x</dt>
<dd>A \(T \times K\) numeric matrix. In the context of a
design matrix for a GLM analysis of task fMRI, \(T\) is the number of time
points and \(K\) is the number of task covariates.</dd>
<dt>doRows</dt>
<dd>Scale the rows instead? Default: <code>FALSE</code>.</dd></dl>
