%% Symbolic Function of Multiple Variables
% Create a symbolic function of multiple variables f(x,y) using syms. Check whether the unassigned symbolic function f is of type 'symfun'.

syms f(x,y)
TF = isSymType(f,'symfun')

% Check whether f depends on the exact variable x.

TF = isSymType(f,'symfunOf',x)

% Check whether f depends on the exact sequence of variables [x y].

TF = isSymType(f,'symfunOf',[x y])

% Check whether f depends on the variable x.

TF = isSymType(f,'symfunDependingOn',x)
