Maple Toolbox for Matlab

 How to do this : sin(x)*cos(y)+sin(y)*cos(x) = sin(x+y) ?.

i used " simple" command but not done.
i'm using MAPLE TOOLBOX FOR MATLAB V11.0, run this command in MATLAB window
Thanks

In Maple itself, it would be:

> combine(sin(x)*cos(y)+sin(y)*cos(x),'trig');
                                  sin(x + y)

You will need to find the appropriate rewrite into the Matlab interface
for Maple. (Note: In Maple, 'trig' is an unevaluated symbol named trig,
not the character string "trig".)

Hi,
Try to call the 'maple' function instead! It will access the Maple kernel from Matlab:
maple('combine','sin(x)*cos(y)+sin(y)*cos(x)','trig')
which returns sin(x+y) under Matlab
Regards,
Vincent
