CHEBYSHEV1_RULE is a MATLAB program which generates a specific Gauss-Chebyshev type 1 quadrature rule, based on user input.
The rule is written to three files for easy use as input to other programs.
The Gauss Chevbyshev type 1 quadrature rule is used as follows:
Integral ( A <= x <= B ) f(x) / sqrt ( ( x - A ) * ( B - x ) ) dx
is to be approximated by
Sum ( 1 <= i <= order ) w(i) * f(x(i))
chebyshev1_rule ( order, a, b, 'filename' )where
