how to write a symbolic function that subtracts its first value to each value in matlab

In this code, x is defined as a symbolic variable using the syms function. The symbolic function f is then defined as the subtraction of x from its first value x(1).

You can use the symbolic function f to perform the subtraction for specific values of x or work with it symbolically in MATLAB.
