Method Detail

at

double[] at(double t,
            int c,
            double[] ret)

Compute the c'th derivative of all dimensions at t. Default implementation via iteration over at(double, int, int).

Parameters:

t - t-value (input)

c - derivative (0=location, 1:speed, ...)

ret - return value container

Returns:

the c'th derivative at t

at

float[] at(double t,
           int c,
           float[] ret)

Compute the c'th derivative of all dimensions at t.

Parameters:

t - t-value (input)

c - derivative (0=location, 1:speed, ...)

ret - return value container

Returns:

the c'th derivative at t

at

double at(double t,
          int c,
          int dim)

Compute the c'th derivative of the given dimension at t.

Parameters:

t - t-value

c - derivative (0=location, 1:speed, ...)

dim - dimension (0,1,2,...)

Returns:

the c'th derivative at t

dim

int dim()
