The resolution of the systems of differential equation using Rosenbrock method

The resolution of the systems of differential equations

dY(t)/dt=AY(t)+B, t∈[t0,tf],
Y(t0)=Y0.

using Rosenbrock method.

Inputs : A : size matrix (n,n).
B : size matrix (n,s).

Y0 : size matrix (n,s).
t0,tf : temps.

Output: Y(1,:) : solution Y1,1(t) of the systems of differential equation.

From the test, this method was found to be faster than the normal method known in Matlab (ode23s) in terms of time to calculate the approximate solution.
