The solidus is not fit for matrix. How can I fix it?
Best Answer
You could scale
/
using\scalebox{<factor>}{<stuff>}
from thegraphicx
package:Note that this scales
/
both vertically and horizontally, increasing the width of the symbol as well. To minimize this, I've only scaled\Bigg/
. To see the difference, consider (say)\raisebox{-2ex}{\scalebox{4.5}{/}}
.Another alternative could be to rotate a vertical rule by (say) 15 degrees clockwise. For this you could use
The above vertical rule has a fixed width of
0.4pt
, which you can change to your liking.
