What does it mean to have a free variable? What norms do not have a gradient at x = 0? What is the meaning of range in linear algebra? What does a free variable mean? What is the meaning of forcing in mathematics? What is the definition of a limit? What are the definitions of on...
Gilbert Strang, Introduction to Linear Algebra, 1.1 What do physicists mean then when they say a certain (x,y,z)(x,y,z) isn't a vector? Certainly any element of R3R3 is a vector. The sources talk about being the same under coordinate transforms: but of course any transform of ...
Unlike a std::vector<> and other C++ standard containers, however, which may also just have fixed class sizes and contain pointers which point to their storage memory, a span does not own the memory it points to, and will never delete it nor resize it nor allocate new memory automatically...
What does Ax = b mean ? 【Abstract】This paper concentrates on the meaning of the form AX=b. As an essential part of the chapter Linear Equations in Linear Algebra, the diverse uses of it makes it confusing for readers to understand. After permenently thinking, I summarize some of the ...
"has 5 5 dimensions, and therefore has five vectors in its basis", i assumed you were aware that a set of five vectors in a five-dimensional vector space does not necessarily span the entire five-dimensional space, but might span a subspace of fewer dimensions,and ...
(output). the goal is to find the best-fit line that minimizes the sum of squared differences between the observed and predicted values. this line can then be used to make predictions or draw conclusions about the data. what does it mean by linear programming? linear programming is a ...
What Does This Subspace Expression Mean? Hi everyone, I was hoping someone could help me with something. Could someone explain to me exactly what this expression means: H = {(a+b) + (a - 2b)t + bt^2 | a E R, b E R} the purpose is to find the dimension of the given subspace...
Forum: Linear and Abstract Algebra C Vector subspace notation question when dealing with vector subspaces, an example of a question asks: if x=(a,a,b)T (T is really a superscript) is any vector in S, then... what does that T superscript notation mean? does that mean transpose? Tha...
This estimate is quite explicit, does not need the subtraction of the mean value, does not need convexity of , but also does not obey the scaling (which is of no surprise since we used the condition which also does not obey this scaling). In dimension the estimate takes the simpler form...
