I need help writing a matlab code that can solve this system of equations, I tried using a generator like symbolab emathhelp etc but none of them work, any help would be greatly appreciated

Hi @Ryan Boulden

Unable to solve because there are 8 variables, but only 4 equations.

Ignore the x’s it’s just A’s and phis

Do the dotted x represent distinguished variables or do they represent derivatives?

[Walter Roberson]

You show x1(0) which is the value of function x1 in some parameter, when the parameter value is set to 0. Unfortunately that is not enough for us to fully define the functions. Suppose for example you have

g(t) = -5*t^3 + 2*t^2 - 7*2 + 2

then when you evaluate g(0) you would just get 2 which does not give you any information about how the equation varies in t.
