Webfirst-order ordinary differential equations. In vector notation, we may write such a system as dx(t) dt = v(x(t);t), (1) where x is an n-dimensional vector-valued function and v is an n-dimensional non-linear vector field specified by the model in question. As a mental image, we might think of x as the location of a test WebA X + X B + C = 0. The matrices A, B, and C must have compatible dimensions but need not be square.
