I have two adjacent terms in a LaTeX equation, and I'd like the brackets around both to scale to the height of both terms.
For example \left[ a \right] \left[ \frac{b}{c} \right]
generates:
I'd like all four brackets to both be the same height.
In general, you could use
\left[\vphantom{\frac{b}{c}}a\right] \left[\frac{b}{c}\right]
using \vphantom
to obtain the appropriate height of something without introducing an unnecessary width insertion. Alternatively, use fixed-sized scaled delimiters using "big"-variants. From the amsmath
user guide (section 4.14.1 Delimiter sizes, p 15):
\biggl[a\biggr]\biggl[\dfrac{b}{c}\biggr]

package, I had a similar question and got this excellent answer: tex.stackexchange.com/a/125722/19326. (It was about Images), but if you look inside thescalerel
documentation you will find it talking about symbol scaling too, right in teh beginning of chapter 2 and chapter 3.\stretchrel
might be what you need. This is overkill if it is just for one occurence though.\left
