Change standard tex output of multiplication in maxima
We try to change the way maxima translates multiplication when converting to tex.
By default maxima gives a space: ,
We changed this to our own latex macro that looks like a space, but in that way we conserve the sementical meaning which makes it easier to convert the latex back to maxima.
:lisp (setf (get 'mtimes 'texsym) '("\invisibletimes "));
However, we have one problem, and that is when we put simplification on. We use this for generating steps in the explanation of a solution. For example:
tex1(block([simp: false], 2*3));
Of course when multiplying numbers we can want an explicit multiplication (cdot).
So we would like it that if both arguments of the multiplication are numbers, that we then have a cdot when translating to tex.
Is that possible?

Yes, if there is a function named by the TEX property, that function is called to process an expression. The function named by TEX takes 3 arguments, namely an expression with the same operator to which the TEX property is attached, stuff to the left, and stuff to the right, and the TEX function returns a list of strings which are the bits of TeX which should be output.
You can say :lisp (trace tex-mtimes) to see how that works. You can see the functions attached to MTIMES or other operators by saying :lisp (symbol-plist 'mtimes) or in general :lisp (symbol-plist 'mfoo) for another MFOO operator.
So if you replace TEX-MTIMES (by :lisp (setf (get 'mtimes 'tex) 'my-tex-mtimes)) by some other function, then you can control the output to a greater extent. Here is an outline of a suitable function for your purpose:
(defun my-tex-mtimes (e l r)
(if $simp
(tex-nary e l r) ;; punt to default handler
(tex-mtimes-special-case e l r)))
You can make TEX-MTIMES-SPECIAL-CASE as complicated as you want. I assume that you can carry out the Lisp programming for that. The simplest thing to try, perhaps a point of departure for further efforts, is to just temporarily replace TEXSYM with cdot. Something like:
(defun tex-mtimes-special-case (e l r)
(let ((prev-texsym (get 'mtimes 'texsym)))
(prog2 (setf (get 'mtimes 'texsym) (list "\cdot "))
(tex-nary e l r)
(setf (get 'mtimes 'texsym) prev-texsym))))
