Based on my understanding of the sympy codebase structure and the issue described, I need to create a patch that: 1. Adds a `_print_Trace` method to the LaTeX printer that properly formats Trace expressions 2. Uses `\operatorname{tr}` as suggested in the hints (puts proper spacing) 3. Properly prints the inner expression using the LaTeX printer Here's the patch: --- a/sympy/printing/latex.py +++ b/sympy/printing/latex.py @@ -1510,6 +1510,10 @@ class LatexPrinter(Printer): def _print_MatrixBase(self, expr): lines = [] + def _print_Trace(self, expr): + mat = expr.arg + return r"\operatorname{tr}\left(%s \right)" % self._print(mat) + def _print_MatrixElement(self, expr): return self.parenthesize(expr.parent, PRECEDENCE["Atom"], strict=True) \ + '_{%s, %s}' % (expr.i, expr.j)
