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 t...
What I did: using matlabFunction, I obtained an expression for y, then substituting q into it, I obtained them numerically. After that I could find points on the X axis where y > 0. But then how to substitute all this into vpasolve and get an expression for it - I don't understand...
I dont understand well the integral expression and limits of integration. To solve numerically integrals in MatlabR 2012a (or previous version).

I want to sovle two equations with two variables δ, Δ numerically. So I tried to use ode45 but I didnt find anyone have the problem that second order of two variables are in one equation. This is a simpified version of the equation. M*(d^2δ/dt^2+d^2Δ/dt^2)=2δ+1...
I don't have a formula to integrate. As I know, integral2 should take a formula through an input function handle. I have numerical data. The data are generated on the disc area through some calculations, and then need to be integrated numerically. Matt J on 21 Feb 2022 ...
