    Graduate Is MATLAB's ode45 Suitable for Solving 2D Coupled Nonlinear ODEs?

    Thanks a lot JJacquelin and AlephZero. You are right, apart from lack of clear cut modeling, I am still new to nonlinear stuff. Let me elaborate the problem & I hope that may help you in helping me. In simplified form, I am trying to model the vibration of a mass on moving belt along with...

    Graduate Is MATLAB's ode45 Suitable for Solving 2D Coupled Nonlinear ODEs?

    Ohhhhh... I have to solve them anyway...what if I provide x(0), y(0), dx(0)/dt & dy(0)/dt? Any other way I can make the system bit simple?

    μ(v_r ) is co-efficient of friction as a function of relative velocity. K is a constant. 〖VB〗^2 is VB*VB and is a variable. The whole thing can be expressed as: [K *VB*VB* (dy/dt)]/ v

    Can anyone please suggest whether I can use MATLAB ode45 for the numerical solution of the following equations? mx ̈+ c_x x ̇ + k_x x= F_x0+ μ(v_r ) (K 〖VB〗^2 y ̇/v) sgn(v_r ) my ̈+ c_y y ̇+ k_y y= F_y0+ (K 〖VB〗^2 (y/v) ̇ ) Where, m, c_x, k_x, c_y, k_y, F_x0, F_y0, K, v are known...
