Bookmark or Share- math mode - Writing multiplication dots - TeX - LaTeX Stack Exchange@bjartmar: This might be language specific. In German, for example, scalar multiplication is written with a \cdot. We also use this same symbol for the dot product, although some books prefer the \circ. And we generally use \times for the cross product (vector product). Personally, I would never write 2(2)=4 or (2)(2)=4 in a text, even as a ...
- Smaller `\\odot` for pointwise product - LaTeX Stack ExchangeI'd like to adjust $\odot$ to take up roughly similar amounts of space and ink as $+-*\times\div\circ\cdot$, while also exactly matching their vertical centering and horizontal padding. Bonus points if this adjustment does not require importing any new latex packages, so could be tossed into Markdown Latex in a pinch.
- math mode - Making a thicker \cdot for dot product (that is ... - TeXThe vertical position is fixed to center the symbol vertically around the math axis as \cdot and \bullet do. The width of the symbol is not the scaled down width of the \bullet (with scaled down side bearings), but a little larger width of \cdot. The scale and width factor can be configured by macros \bigcdot@scalefactor and \bigcdot@widthfactor.
- Which dot character to use in which context? - TeX - TeX - LaTeX Stack ...WP Multiplication article uses \cdot for scalar multiplication. WP says the matrix dot product should be written using the "bullet operator" character, like "a ∙ b". The WP Dot product article uses the LaTeX \cdot character for dot products.
