Hi I want to numerically integrate some function in Matlab using "integral". Say f_int(x). However, f_int can not handle vector inputs. This seems to cause "integral" troubles? Any ideas how to quickly fix this, w/o having to rewrite f_int(x)? Thanks a lot. M ...
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...
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...
