In the first stage, the desired spatial correlation characteristics between M transmitting antenna ports and L probe antennas are realized by a fixed matrix connection.
Let C be a fixed positive definite matrix and let matrix H solve matrix equation (6).
Let C be a fixed positive definite matrix and let matrix H solve the matrix Lyapunov equation (6).
Let (rho(A)<1), C be a fixed positive definite matrix and let matrix H solve the corresponding Lyapunov matrix equation (6).
Still, the non-redundant information carried by the Current Density Norm feature drops substantially -- a problem that may be caused by the use of a fixed matrix Γ J λ which had been determined on the RT setup of 115 electrodes.
One-point calibration was performed using a fixed matrix-matched standard (tomato, see Results and discussion section) at a level corresponding to five times the LOQ.
X i is a fixed effects design matrix that includes indicators for diet group (1, 2), assessment time (after each 1.5 kg fat loss, and potential covariates (age) or confounders (disease stage, BMI).
where n → denotes the outerward normal to ∂B G (e, m), and A is a fixed positive semi-definite matrix (see [4, 13]).
It can be explained that the fixed matrix transform can be regarded as some special vectors in PCA.
By comparing the expressions (76) and (78) with the analytical results in [7], it is clear that the fixed matrix λ 2 A in the expressions for the conventional DRLS algorithms has been replaced by the matrix F i) in the expressions (76) and (78), which is weighted by the matrix Λ i.
