Hello to all,

I am using sagetex and latex to produce several variations of an exam, using sagetex and Latex with a script that makes several iterations. I do this:

`var('x,y,z')`

`v = vector([x,y,z])`

`a = vector([1,-2,-1])`

These will chgnage from one iteration to the next.

`sortie = str(latex(a.dot_product(v)))`

This leads to `x - 2 \\, y - z`

, which is correct, and I would like to turn into `\bbm{x} -2 \\, \bbm{y} - \bbm{z}`

for the Latex processing so that x,y and z are whohn like vectors.

Suggestions?
