James Tursa on 23 Mar 2017 Eg if you are using ode45 then simply reshape F and the initial Fo into column vectors.
The left-division method is based on Gauss elimination. Second write the equations in a matrix form To write the equations in the matrix form Ax b where x is the vector of unknowns you have to arrange the unknowns in vector x the coefficients of the unknowns in matrix A and the constants on the rigth hand of the equations in vector b.
