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...

It is demonstrated that the Romberg method gives a high precision for the price of the good time performance, and therefore represents a competitive alternative to MATLABs standard functions for numerical integration.doi:http://dx.doi.org/Kačeňák Martin...

Now if you integrand depends on To, then the only way to use 'ArrayValued' is to transform the problem so that each integral has the same upper bound. This might or might not be a good thing to do, depending on how efficient you can make the tra...
