Branching Statements on Solving Function My Soluti Write a MATLAB program to evaluate the function y(x) = Inx for any user-specified value of x, where x is a number. 1.0 (note that In is the natural logarithm, the logarithm to the base e). Use an if structure to verify that the value passed to the program is legal. If the value of x is legal, calculate y(x). If not, write a suitable error message and quit.
