    Perform a low-rank approximation of the Gaussian process using the Nystrom method.

    Perform a low-rank approximation of the Gaussian process using the Nystrom method. The sample points used for the nystrom method are sampled using the given sample.

    gp

    The gaussian process to approximate

    sampler

    determines which points will be used as samples for the nystrom approximation.

    numBasisFunctions

    The number of basis functions to approximate.
