on a rectangle area. It has no sigularity point in the area and seems to be a perfect candidate to use dblquad. My question is how to evaluate the accuracy of the numerical value that Matlab provided to me. Without knowing the exact value of the integration, how can one justify the si...
Hello: I have not been able to find out what is the underlying quadrature formula in Matlab's builtin function integral. I think that quad uses Simpson, quadl a Gauss-Lobato formula and quadgk the Gauss-Kronrod formula G7K15, and all of them use some kind of adaptative scheme. What ...
Numerical integrationRomberg methodMatlabtrapezoidal ruleSimpsons rulespeed-upA method suggested by Romberg in 1955 is shown to be a very efficient, accurate and fast. In this paper an implementation of the Romberg method in MATLAB is discussed and illustrated using example. Two modifications of the...
