When you multiply a vector by a number, this is called the scalar multiplication. The mat"" custom string literal. Therefore, operators in MATLAB work both on scalar and non-scalar data. The jacobian function is used in MATLAB to find the Jacobian matrix of any function (vector or scalar). The arithmetic operators have M-file function equivalents, as shown: types): char versus string. What is the difference between String and string in C# Here's a short example.
