M-files to solve numerical integration

  1. Mar 21, 2012 #1
    1. The problem statement, all variables and given/known data

    Numerical integration using MATLAB m-files
    Find the area under the curve of:
    using trapezium rule
    2. Relevant equations

    g(x) = x^2 from x=0 to x=2
    Area of a trapezium = h/2(a+b)

    3. The attempt at a solution

    You can use the command "trapz", look it up in the help files. It integrates a numerical sequence using the trapezoidal rule.
