% Example 10.3a (Physics 330)

% define the function to be integrated in fint.m

function f=fint(x)

%*********************************************************
% Warning: Matlab will do this integral with arrays of x,
% so use .*, ./, .^, etc. in this function.  If you forget
% to use the .-form you will encounter the error:

%       Inner matrix dimensions must agree.

f=cos(x).*exp(-x);
