%Input - f is the integrand
% - a and b are upper and lower limits of integration
% - M is the number of subintervals
%Output - s is the trapezoidal rule sum
%If f is defined as an M-file function use the @ notation
% call s=trprl(@f,a,b,M).
%If f is defined as an anonymous function use the
% call s=trprl(f,a,b,M).
