I want to define a symbolic vector in Matlab, but every element of the vector should be created through a symbolic function. Here, f is not a symbolic function: it has been transformed into an anonymous function with options that instruct the anonymous function to pack x1, x2, x3 into a single column vector. This array is then placed in a cell array when specifying the input arguments to the generated function. If f is a symbolic function of type symfun, then args is returned as a symbolic variable or a vector of symbolic variables of type sym.
