Function Documentation

setup_recon_lsr()

void setup_recon_lsr	(	recon_t *	recon,
		const parms_t *	parms
	)

Setup the least square reconstruct by directly inverting GA matrix. The reconstructor is simply the pseudo inverse of GA matrix:

\[\hat{x}=(G_a^TC_g^{-1}G_a)^{-1}G_a^TC_g^{-1}\]

This is very close to RR except replacing GX with GA.

We use the tomograhy parameters for lsr, since lsr is simply "tomography" onto DM directly.
