error: int = quadc('Fun',xlow,xhigh) or int = quadc('Fun',xlow,xhigh,tol) or int = quadc('Fun',xlow,xhigh,tol,trace,p1,p2,....) This function works just like QUAD or QUAD8 but uses a Gaussian-Chebyshev quadrature integration scheme. The Gauss-Chebyshev Quadrature integrates an integral of the form xhigh Int ((1/sqrt(1-x^2)) fun(x)) dx -xhigh This routine ignores xlow
