MATLAB程式問題

昨天有問過了有人反應沒辦法一次po完所以在問一下一、請以MATLAB撰寫一個程式

使用遞增搜尋法(increment research)找出下列函式在區間【3

6】以及【3

100】的根(注意:非根的上下界限)f(x)=sin(x) cos(x)這次點數有喔
這是遞增搜尋法(increment research)的程式(Steven C. Chapra: Applied Numerical Methods with MATLAB for Engineers and Scients書中程式)function xb = incsearch(func

xmin

xmax

ns)% xb = incsearch(func

xmin

xmax

ns):%   finds brackets of x that contain sign changes of %   a function on an interval% input:%   func = name of function %   xmin

xmax = endpoints of interval%   ns = (optional) number of subintervals along x%        used to search for brackets % output:%   xb(k

1) is the lower bound of the kth sign change%   xb(k

2) is the upper bound of the kth sign change%   If no brackets found

xb = [].if nargin
