Im creating program to create the steepest ascent but can't get pass
the following errors,

??? Error using ==> sym.sym>notimplemented at 2514
Function 'gt' is not implemented for MuPAD symbolic objects.

Error in ==> sym.sym>sym.gt at 792
notimplemented('gt');

Error in ==> steepestA at 39
end

Does anyone know what the error mean? How can I fix my program to get
rid of this error?

Thank you!

As the error message says, the greater-than operator is not defined for
symbolic expressions. [After all, how can you answer the question x > y if
x and y are arbitrary symbolic expressions?] If you want to determine if
your expression is greater than some other value, convert the expressions to
some type for which the greater-than operator is defined (liked DOUBLE.)
