NAME

    cevalCinte --- construct matrix of partial integrals of a B-spline basis

FUNCTION

This is needed to compute the cumulative baseline hazard. This function updates the input matrix cinte, so that cinte[i,j] contains the integral of the j-th B-spline basis function of order ord, defined on the given knots, from 0 to x[i]. It's just a wrapper for cevalCinte2 that evaluates the entire matrix.

SYNOPSIS

311 void cevalCinte(double *cinte, double *x, int *nx, double *knots, int *ord, int *K, double *binte)

INPUTS

    cinte     output matrix of dimension nx x nj
    x         vector of observations at which to evaluate
    nx        length of x
    knots     vector of knot positions, length nj+ord
    ord       order of the spline
    binte     vector of integrals of each B-spline basis function, see cevalBinte
