MATLAB M-file that takes values of x and returns values ¯u(x). Observe in this M-file that the guess for fzero() depends on the value of x. function value = degwave(x) %DEGWAVE: MATLAB function M-file that takes a value x %and returns values for a standing wave solution to %u t + (uˆ3 - uˆ2) x = u xx guess = .5; if x < -35 value = 1; else 5
