The integral of an absolute value function is evaluated by removing the absolute value symbol by splitting the integral limits to handle the piecewise nature of an absolute value function. For instance, the definite integral ∫−11x dx is calculated as ∫−10−x dx+∫01x d...
The notion of \\(L^r\\) -variational measure generated by a function \\(F\\in L^r[a,b]\\) is introduced and, in terms of absolute continuity of this measure, a descriptive characterization of the \\(H\\!K_r\\) -integral recovering a function from its \...
Integrand, specified as a function handle, defines the function to be integrated over the planar regionxmin≤x≤xmaxandymin(x) ≤y≤ymax(x). The functionfunmust accept two arrays of the same size and return an array of corresponding values. It must perform element-wise operations. ...
formed of constituent parts; united of or involving an integral involving or being an integer n/ˈɪntɪɡrəl/ the limit of an increasingly large number of increasingly smaller quantities, related to the function that is being integrated (the integrand). The independent variables may be...
It accepts a vector x and returns a vector y, the function fun evaluated at each element of x. Limits a and b must be finite. Parameterizing Functions explains how to provide additional parameters to the function fun, if necessary. q = quadl(fun,a,b,tol) uses an absolute error ...
The integral3 function attempts to satisfy: abs(q - Q) <= max(AbsTol,RelTol*abs(q))where q is the computed value of the integral and Q is the (unknown) exact value. The absolute and relative tolerances provide a way of trading off accuracy and computation time. Usually, the relative...

When the curve is below the axis the value of the integral is negative!So we get a "net" value.If we want a total area (say we wanted to paint it) we can use the absolute value function abs(). Or manually find where the curve crosses the axis and then work out separate integrals...
