How can I change the size of \vert accordingly like \left and . . . - TeX The first problem can be solved, superficially, by changing \vert to \middle\vert Fixing the second problem requires inserting \; ("thickspace") on either side of \middle\vert Entering the full expression can be streamlined, to a degree, by defining a macro \f as follows:
tex core - Problem with | (\vert) in LaTeX - LaTeX Stack Exchange \left\vert a \right\vert Now the problem I could easily write: \vert a \vert But in case when instead of 'a' there is some large expression, the vertical lines will not be tall as the expression, but stay the small That is what \left and \right are for Is there any easy way to do this that I don't see here, or do I need to parse the MathML
math mode - Use `\big\vert f(x) \big\vert` or `\big\lvert f(x) \big . . . In short, \bigl\vert <some math atom> \bigr\vert is definitely better than \big\vert <some math atom> \big\vert, typographically speaking, as it produces the correct spacing in all cases A final remark, prompted by a comment from barbara beeton: For the code examples used here, it's not necessary to increase the size of the vertical bars
Using \big| and \right| versus \bigr\rvert and \right\rvert - TeX \left\vert or \right\vert: the first of these expands to \left \delimiter "026A30C TeX already knows that a left delimiter is being asked for, and therefore ignores the first digit of the number "026A30C, and uses the remaining digits to learn where to find the glyph(s) it needs The effect of \right\vert is analogous
Math symbol question: Vertical bar for evaluated at . . . How to stretch a vertical bar to be tall: To stretch a vertical bar to be tall, such as to plug in values into a definite integral's antiderivative, add an invisible vertical bar on the left with \left , and a visible vertical bar on the right with \right|
Why does \big\mid not work? - TeX - LaTeX Stack Exchange The commands \bigl\vert, \bigm\vert, and \bigr\vert are semantically symmetric Incidentally, the triplets of commands \bigl\lvert \bigl\vert \big\lvert and \bigr\rvert \bigr\vert \big\rvert, respectively, produce the same output It's the command \mid that's a bit of an outlier, semantically speaking
symbols - Why is \mid so called? - TeX - LaTeX Stack Exchange The LaTeX commands \\mid and \\vert may be used to make a vertical bar I can appreciate that \\vert is short for vertical, but why \\mid? Is it short for middle? and if so, middle of what?
How to write norm which adjusts its size? - TeX - TeX - LaTeX Stack . . . @VincentNivoliers - Note that \Vert is equivalent to \| The l and r prefixes inform TeX that the commands \lVert and \rVert should be given math codes mathopen and mathclose, respectively (TeX has no way of knowing how to modify the default math code of \Vert ) –
