Latex x Tex function



Just a suggestion. Possibly most people use Latex rather than Tex. I
am not suggesting anything like that Latex is worst or better than
pure Tex. Possibly pure Tex is really better than Latex but I started
with latex ...

In this case the tex function could be improved or maybe created a
latex version in a not so near future. 

Firstly I must refrain that my migration from Mathematica is being
incredibly smooth and also that the Tex output from Maxima is
ABSOLUTELY better than the equivalent Mathematica function. 

I will present a Maxima session as an example

C83) mat:MATRIX([X+3*COS(X)^2-SIN(X)^2,0],[X+3*COS(X)^3-SIN(X),1]);
					[      2	   2	       ]
					[ - SIN (X) + 3 COS (X) + X  0 ]
(D83) 				        [ 			       ]
					[		  3	       ]
					[ - SIN(X) + 3 COS (X) + X   1 ]
(C84) trigreduce(%);
				  [ COS(2 X)	  COS(2 X)   1	      1	    ]
				  [ -------- + 3 (-------- + -) + X - -	  0 ]
				  [    2	     2	     2	      2	    ]
(D84) 				  [ 					    ]
				  [    COS(3 X)	  3 COS(X)		    ]
				  [ 3 (-------- + --------) - SIN(X) + X  1 ]
				  [	  4	     4			    ]


>>>> Here  I obtain the Tex output


(C85) tex(%);
$$\pmatrix{{{\cos 2\>X}\over{2}}+3\>\left({{\cos 2\>X}\over{2}}+
 \mathchoice {{1}\over{2}}{{1}\over{2}}{1//2}{1//2}\right)+X-
 \mathchoice {{1}\over{2}}{{1}\over{2}}{1//2}{1//2}&0\cr 3\>\left({{
 \cos 3\>X}\over{4}}+{{3\>\left(\cos X\right)}\over{4}}\right)-\sin X
 +X&1\cr }$$
(D85) 						     FALSE
(C86)
