The phrase "a robust matrix of" is correct and usable in written English.
It can be used to describe a strong and well-structured framework or system that consists of various interconnected elements or components.
Example: "The research team developed a robust matrix of strategies to address the complex challenges faced by the organization."
Alternatives: "a strong framework of" or "a solid structure of".
This dysregulation of MMP/TIMP system could lead to a net activation and a robust matrix degradation of type IV collagen within the basement membrane leading to a more robust laying down of new and reassembled type IV collagen as well as other BM matrix constituents [ 60].
Consequently, a robust matrix mineralization was achieved, covering >90% of the culturing surface area.
We applied the empirical option for the mixed effects procedure in SAS, also known as the "sandwich" estimator which computes a robust variance covariance matrix of the fixed effects parameters using an asymptotically consistent estimator [56 59].
Robust counterparts of the correlation matrix based detectors are obtained by substituting a robust correlation matrix estimate as it was discussed in Section 2 (12) mathbf{R}_{r} = left{ begin{array}{ll} mathbf{R},& text{if} mathbf{x} leq eta kappa eta,& text{otherwise} end{array} right.
A robust variance matrix calculation is utilised that relaxes the assumption of independence within groups.
In this paper an H∞ approach to the design of a robust T-matrix algorithm is proposed, with the aim of developing a systematic approach to the design of active vibration control laws for helicopters.
Then, we obtain the noise robust matrix D ′′ replacing the term U ij of Eq. (19) by a new transformed signal subspace matrix (boldsymbol {U}^{prime }_{ij}(theta)).
For a q-dimensional multivariate vector for i=1,…, n, the rMd is defined as, (7) where C Sn, a robust estimate of the covariance matrix, is obtained from the robust principal component analysis of the n× q quality matrix, and is a vector of medians of the five metrics.
The data is however contaminated by the impulsive noise so the first thing to do is to obtain a robust estimate of the correlation matrix.
Because of its generality, a robust estimator of the scatter matrix over the CES distributions will not rely on any additional estimates of unknown extra parameters, as it is for the matched ML estimator in Eq. (4) that depends on the estimates of λ and η.
