Here is how I put in the proper latex command:
set_tex_environment(matrix,concat("\\begin{bmatrix}",""),"\\end{bmatrix}~%")$
texmatrix(l) := block([s,i,n,m:l],
n : length(m),
s : tex1(rlist(m[1])),
for i:2 thru n do ( s : concat(s,"\\\\",newline,tex1(rlist(m[i]))) ),
s : concat(s,newline),
s)$
texput(matrix,texmatrix)$
