Samples continuous points in an interval. It allows for both linear and
uniform random sampling. It is also possible to draw points only in the
simplex of the interval.
Inputs:
- lo : lower bound (column of length D)
- hi : upper bound (column of length D)
- N : number of points to sample
- useSimplex : put 1 if you want to sample from the simplex of the bound, 0 otherwise
- linearly : put 1 if you want the points to be linearly spaced, 0 otherwise
Outputs:
- points : D-by-NN matrix with random points, where NN >= N
