Question
I was given these set of differential eqs. dy(1)=y(2), dy(2)=y(3), dy(3)=y(4), dy(4) =-w/(E*I), with boundary conditions: y1(0)=0, y3(0)=0, y1(L)=0, y3(L)=0. I have to use bvp4c to solve it but I can't do it here is my code. What am I doing wrong?
function dy=odefun(x,y) w=100; E=29000000; I=285; dy=[y(2); y(3); y(4); -w/(E*I)] function res=bcfun(y0,yL)...

i was given these equations to solve with mass matrix ( dy(1)=y(2), dy(2)=0, dy(3)=y(4), dy(4)=-g), initial conditions y(1)=0, y(2)=v(cosa), y(3)=0, y(4)=v(sina) but i dont know how to use it can someone help me get started
i dont know what is the format that i have to use to solve differential equations with mass matrix please help me

I have been asked to solve this set of differential equations using mass matrix but i dont know how it works, the eq. are dy(1)=y(2), dy(2)=0, dy(3)=y(4), dy(4)=-g, with initial conditions: y1(0)=0, y2(0)=v*cos(a), y3(0)=0, y4(0)=v*sin(a) help me
I dont have any idea o how to use the mass matrix, help me.
