CLENSHAW_CURTIS_RULE is a MATLAB program which generates a Clenshaw Curtis quadrature rule based on user input.
The rule is written to three files for easy use as input to other programs.
The standard Clenshaw Curtis quadrature rule is used as follows:
Integral ( A <= x <= B ) f(x) dxis to be approximated by
Sum ( 1 <= i <= order ) w(i) * f(x(i))
clenshaw_curtis_rule ( order, a, b, 'filename' )where
