使用Matlab 2013b，我运行了命令class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
let data = ["111111", "2222222","3333333"]
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return(data.count)
}
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.lb1.text = data[indexPath.row]
cell.stepper.tag = indexPath.row
cell.stepper.addTarget(self, action: #selector(stepperA(sender:)), for: .valueChanged)
return (cell)
}
func stepperA (sender: UIStepper){
print("stepper \(sender.tag) clicked. Its value \(sender.value)")
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
，我得到了结果：
mex -setup我的问题是，在Matlab2016a下我看不到这条消息 - 我只得到以下结果：
>> mex -setup
Welcome to mex -setup. This utility will help you set up
a default compiler. For a list of supported compilers, see
http://www.mathworks.com/support/compilers/R2013b/win64.html
Please choose your compiler for building MEX-files:
Would you like mex to locate installed compilers [y]/n? n
请，我如何看到消息
>> mex -setup
MEX configured to use 'Microsoft Visual C++ 2012 (C)' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the
new API. You can find more information about this at:
http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.
To choose a different language, select one from the following:
mex -setup C++
mex -setup FORTRAN
非常感谢。
答案 0 :(得分：1)
要更改默认C ++编译器，请键入：
mex -setup cpp
通过这种方式，您可以更改为不同的编译器（如果有的话）。调用mex -setup设置C编译器，可能不同。
