Jacobian
• Jacob(F(x), x, [k])—Returns the Jacobian of the vector function F(x) with respect to the variables in the vector x.
The resulting matrix has length(x) columns.
Arguments
• F is a vector function of the form F(x) written as a column vector of scalar-valued functions, which can have complex values.
• x is a vector of variables for the functions in F.
• k (optional) is an integer argument specifying the number of variables for the Jacobian.
