I wonder how to restore the latex_name attribute of a function or variable after saving to a file
my code is:
fx = function('fxf', latex_name=r'f_x')(y);
eq = fx.diff(y)
then I save the equation with
save(eq,'eq')
In a new session I do
fx = function('fxf', latex_name=r'f_x')(y)
eq=load('eq')
but
show(latex(eq))
does not show the latex expression for f_x but sill stays with diff(fxf(y),y) How can I restore the latex output with "f_x"?
