Exporting a code from Maple to Matlab

I use Matlab for numerical calculations.
But I use Maple for symbolic calculations and after the calculations I usually get piecewise functions in my maple codes.
I think the 3d plots in Matlab is very attractive more than Maple plots. So, I want to export piecewise functions in maple to a Matlab code in order to utilize advantages of plots of Matlab.

We can transform a maple code to Matlab code by using
with(CodeGeneration):
Matlab(u,resultname="w");
. But The code can’ t properly transform to Matlab code.
Could you help me plsI use Matlab for numerical calculations.
But I use Maple for symbolic calculations and after the calculations I usually get piecewise functions in my maple codes.
I think the 3d plots in Matlab is very attractive more than Maple plots. So, I want to export piecewise functions in maple to a Matlab code in order to utilize advantages of plots of Matlab.
