For scalarvalued problems, the function y funx must accept a vector argument, x, and return a vector result, y. The m in sqrtm distinguishes this function from sqrta, which, like a. For analytic solutions, use solve, and for numerical solutions, use vpasolve.
With the two minima being on either side of one of the singularities, you would not be able to integrate this function unless you confined yourself to the area without singularities. Use the matlab comparison tool for diff and merge from external source control tools. Matlab latest, 2015 provides the integral function to numericaly compute integrals of functions. There are no such special functions for higherdimensional symbolic integration. An integral is a mathematical result that represents the area between a function and a plane e.
