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!

The simplest way to do that is use that code:

varargout = builtin('diff',varargin{:});

Also you can looking for something usefull there.

'(heaviside(x)-heaviside(x-1))'*x.^2 means the string '(heaviside(x)-heaviside(x-1))' matrix-multiplied by the element-wise square of x.

Anything in quotes is a string, not symbolic.

Also, matlabFunction() returns a function handle, not a symbolic function.

syms x
(heaviside(x)-heaviside(x-1)) * a

would be a symbolic expression. You could matlabFunction() the result, I suppose.

If you have the Symbolic Toolbox:

>> g = @(x) exp(x^2-2)
g = 
    @(x)exp(x^2-2)
>> syms x
>> diff(g(x))
ans =
2*x*exp(x^2 - 2)
