Minimizing the Sum of Elementwise Products for Three Permutations of a Sequence Unexpected Mixpanel Cookie: Is this an attempted exploit? What's the most common way of writing the all-ones vector, that is, the vector, when projected onto each standard basis vector of a given vector space, having length one? The zero vector is frequently written $\vec{0}$, so I'm partial to writing the all-ones vector as $\vec{1}$, but I don't know how popular this is, and I don't know if a reader might confuse it with the identity matrix. Scientific Notation in SIunitx. \vectorbold \vb{a} !a upright/no The vec command gives a vector with the arrow notation, but it isn’t designed for multiple characters. It looks like an \st{$\chi$} (using the soul package, that is, \usepackage{soul}, but doesn't look so artificial. That is, each row vector acts as a linear map from column vectors to the base field. The above example produces the following output: \[ F = G \left( \frac{m_1 m_2}{r^2} \right) \] Notice that to insert the parentheses or brackets, the \left and \right commands are used. then we need to add a dot to it (\dot), but to avoid a large space between dot and vector we "reduce" height of our vector by 20% (\raisebox not only "raise" its contents but also can change its height and depth). Ce dernier pourra alors être compilé normalement. The optional is a number which represents the rightward kern (in points) applied to the vec arrow, since as the Norm of vector. But in LaTeX, each element of the vector is separated by a newline \\. In that case, you can use the esvect package with its \vv{} command, which gives a larger arrow. Modified 8 years, 3 months ago.
