qr_solve_wrapper()

void qr_solve_wrapper	(	int	m,
		int	n,
		float **	A,
		float *	b,
		float *	x
	)

Wrapper for qr solve.

Possible to use a different solver if needed. Solves a system of the form Ax = b for x.

Parameters

m	number of rows
n	number of columns

active set algorithm for control allocation

Takes the control objective and max and min inputs from pprz and calculates the inputs that will satisfy most of the control objective, subject to the weighting matrices Wv and Wu

Parameters

u	The control output vector
v	The control objective
umin	The minimum u vector
umax	The maximum u vector
B	The control effectiveness matrix
n_u	Length of u
n_v	Lenght of v
u_guess	Initial value for u
W_init	Initial working set, if known
Wv	Weighting on different control objectives
Wu	Weighting on different controls
up	Preferred control vector
gamma_sq	Preference of satisfying control objective over desired control vector (sqare root of gamma)
imax	Max number of iterations

Returns

Number of iterations, -1 upon failure
