MATLAB Online에서 열기 Hi All, i want to get the integral result for bessely function as int{a}{b}int{a}{b}bessely(1, x1-x2)dx1dx2 but when numerically calculate that using Gaussian quadrature points, the va
To make it clear suppose f1(x)=x^3+x-sin(x) and f2(x)=cos(x)-x^-6+1, how can I numerically integrate f1(x)*f2(x)? Thanks John D'Errico 2016년 11월 11일 Sorry, but you are not making sense. You might as well ask how to numerically integrate without using...
In MATLAB Online öffnen I need to solve this equation Numerically. The problem arises as value of is very high (on the order of 10^13), where upon * ^2) is becoming very small and ultimately zero. Can anyone help me to evaluate this using Numerical methods? k,zare not integers nece...
I have an integral that cannot be evaluated symbolically. When I try to do it numerically I want to keep some symbols in the result (to have an output like 10*x1+0.5*x3 where x1 and x3 are symbols) because in a further step I want to build a system of two equations th...

Matlab's ODE solvers are designed to handle smooth functions only, see http://www.mathworks.com/matlabcentral/answers/59582#answer_72047. The only reliable and numerically correct solution is to use event functions to stop and restart the integration at all discontinuities. 0 Co...
The computations execute slowly because Bx and By are represented in an exact form. To speed up your code, since your end goal is a numeric approximation for the solution of your equations, you can use VPA to convert your equations to using high prec...
You can sort a table numerically by parsing the text content of the cells into numbers using functions likeparseIntorparseFloatand then comparing them during the sort. Can I sort multiple columns at once? Yes, you can implement multi-column sorting by modifying the sorting logic to compare multi...
