The design for an fMRI experiment

Convert between representations of a one-way anova with $m$ treatments and $T$ measurements. The vector representation is a T-length integer vector with m distinct integers. The matrix representation is a T by m matrix with a 1 at i,j indicating the i'th measurement belongs to the j'th treatment.

`desvec,perm` |
An integer vector of length T with m distinct non-zero integers. 0 indicates measurements should be discarded. |

`desmat` |
A 0-1 matrix with T rows, m columns. |
