Solve delay differential equations (DDEs) of neutral type
sol = ddensd(ddefun,dely,delyp,history,tspan) integrates a system of delay differential equations of neutral type, that has the form
y '(t) = f(t, y(t), y(dy_{1}),..., y(dy_{p}), y '(dyp_{1}),..., y '(dyp_{q})) | (1-1) |
where
t is the independent variable representing time.
dy_{i} is any of p solution delays.
dyp_{j} is any of q derivative delays.
