MATLAB

The function f (x) = ln(x) is defined over the real numbers (R) for x = (0, ) (though MATLAB will report ln (0) as - Inf). Use an if selection structure to check in the inputted value of x is in the domain of f(x) according to these three cases: Case 1: If the inputted x is not in the domain of (x) (i.e. if x = (-, 0]), use the error command to print an error message to the Command Window. Case 2: If the inputted x is on the domain (0, 1), use the warning command to print a warning to the Command Window stating that the value of f(x) will be less than 0. Case 3: If the inputted x is in the domain [1, ) then calculate and print to the Command Window the value of f(x). Hint: What are the branches in this selection structure? Identify them first, then begin to program the cases. NB: The symbol E is a mathematical symbol that can be interpreted in English as "is an element of." For example, if x = [0, 5] then x is defined within (or "belongs to") that range of numbers. You will likely recall from calculus that parentheses indicate a specific interval does not include the end-point (a so- called "open interval"), while brackets indicate that the interval does include the end point (a so-called "closed interval").
