1. What is open data? What do you mean by data? Put simply, data is facts or statistics collected together for reference and analysis. It can be numbers, text or a combination of both. Data is normally gathered to enable analysis or decision-making of some sort. This could be simple,...
Let's say MathWorks decides to create a MATLAB X release, which takes a big one-time breaking change that abandons back-compatibility and creates a more modern MATLAB language, ditching the unfortu...
Nota- tion that may be less familiar is summarized here: N R A⊤ ker A im A cone A x⊤ xi supp x dim V V⊥ positive integers real numbers transpose of matrix A kernel of matrix A, i.e., ker A = {x | Ax = 0} image of matrix A, i.e., im A = {y | y = Ax ...
where \([A]\|) represents a vector with the group of input signals, and \(G^H\) is the conjugate transpose (or hermitian transpose) of \(G\). \[\gamma_{[A]B}^2(f) = \frac{G_{[A]B}^*[G_{AA}]^{-1} G_{[A]B}}{G_{BB}} = \frac{\begin{bmatrix}G_{A_1B}^*...
(even if one works up to equivalence), making it problematic to give this class the structure of a measurable space; furthermore, even once one does so, one needs to take additional care to pin down what it would mean for a random vector lying in a random vector space to depend “...
What does it mean to reverse the flow of something? Reversing the flow of something, like water or traffic, means changing its direction to move in the opposite path or manner from its current or usual direction. 8 What are common uses of the term 'flip' in everyday language? Common use...
What does opposite mean in spatial terms? In spatial terms, opposite refers to locations or directions that are completely contrary to each other on a given axis or plane. 15 Is reverse always related to physical movement? While often related to physical movement, reverse can also refer to cha...
