Is there a symbol for the inverse? I have been using `X^{-1}`

for my matrix inversions, but this results in the -1 being rather large and taking up almost as much room as another symbol. Is there a built in symbol or trick I should be using?

## Best Answer

If you just want to reduce the size of the

`-1`

term, you could create your own macro called, say,`\inv{...}`

, along the lines of the code below. The screenshot shows the look of both`\inv{X}`

and`X^{-1}`

. (The vertical offset of`1.15ex`

is chosen so that the tops of the`1`

symbols are at very nearly the same height using either`\inv{...}`

or`X^{-1}`

. Feel free to adjust the offset to suit your preferences.)
