x (numpy array) – initial condition, column vector of size 4
earthPressureCoefficients (numpy array) – earth Pressure Coefficients
zeta (float) – slope angle
delta (float) – friction angle
eps_x (float) – scale in x dir
eps_y (float) – scale in y dir
Returns
F (numpy array) – column vector of size 4
