tf.contrib.integrate.odeint_fixed( func, y0, t, method='rk4', name=None )
ODE integration on a fixed grid (with no step size control).
Useful in certain scenarios to avoid the overhead of adaptive step size control, e.g. when differentiation of the integration result is desired and/or the time grid is known a priori to be sufficient.
func: Function that maps a Tensor holding the state
yand a scalar Tensor
tinto a Tensor of state derivatives with respect to time.
y0: N-D Tensor giving starting value of
yat time point
t: 1-D Tensor holding a sequence of time points for which to solve for
y. The initial time point should be the first element of this sequence, and each time must be larger than the previous time. May have any floating point dtype.
method: One of 'midpoint' or 'rk4'.
name: Optional name for the resulting operation.
y: (N+1)-D tensor, where the first dimension corresponds to different time points. Contains the solved value of y for each desired time point in
t, with the initial value
y0being the first element along the first dimension.
ValueError: Upon caller errors.
