Hello,
I need to call function diff (differences between array elements) for array of symbolic variable but matlab is using function diff from matlab symbolic math toolbox. How I can define namespace of calling function?
Thanks!

I thought it is automatic as long as you specify your symbolic variable is properly specified.
>> diff(1:3)
ans =
1 1
>> s=str2sym('2*x')
s =
2*x
>> diff(s)
ans =
2

I guess you have to achieve it in a different way.
>> builtin('diff',s)
Error using builtin
Undefined function 'diff' for input arguments of type 'sym'.
>> builtin('diff',1:3)
ans =
1 1
>> s(2)-s(1)
ans =
1
