Undefined function or Variable error
显示 更早的评论
Hi,
I create a function to use the Mid-point formula to calculate the integral value, but it keeps showing undefined error. I wonder where is the problem, and how I can fix it? Thanks!

x = a:h:b;
However, any current version of MATLAB may have problems with you replacing the function handle f with the result of invoking the function handle. Use different variable names for the function handle and the result of evaluation.
