Description

A text file containing 32-digit values of the first 100 recurrence coefficients for the Jacobi weight function w(x)=(1-x)^a*(1+x)^b, a = -1/2, b = 3/4, is loaded into a Matlab symbolic 100x2 array and the first 10 of them to 24 digits into a symbolic 10 x 2 array and to double precision into another 10 x 2 array.
