Return a design matrix for a linear model with given stimuli and possible polynomial drift terms.
matrix containing expected BOLD repsonse(s) for the linear model as columns
order of the polynomial drift terms
Report more if
The stimuli given in
stimulus are used as first columns in
the design matrix.
The order of the polynomial drift terms is given
order, which defaults to 2.
Confounding effects can be included in a matrix
The polynomials are defined orthogonal to the stimuli given in
design matrix of the linear model
