Method Detail

getTerm

int getTerm(MatrixNd A,
            VectorNd b,
            int rowoff,
            double t0,
            double t1)

Appends the constraints for this term to the constraint matrix A and offset vector b. For inequality constraints, A and b define the constraints

 A x >= b
 

while for equality constraints, they define the constraints

 A x = b.
 

Parameters:

A - quadratic program constraint matrix

b - quadratic program offset vector

rowoff - row offset within A and b where the constraints should be added

t0 - time at start of step

t1 - time at end of step

numConstraints

int numConstraints(int qpsize)

Returns the number of constraints associated with this term.

Parameters:

qpsize - size of the quadratic program. For the tracking controller, this is the number of excitation values being used,
