Matlab Error : Missing domain attribute 'min'

Question

when I use in Matlab:

symmin=@(x,y)feval(symengine,'min',x,y);

symmin(3,4)

ans=

3

but if I want to find the minimum of a vector:

symmin=@(x)feval(symengine,'min',x); % or 

symmin=@(x)feval(symengine,'min',x(1:10));

a=1:10;

symmin(a)

error using mupadengine/feval (line 187)

Missing domain attribute 'min'.

Can you explain me why?
