在Matlab中使用nlfilter函数时如何禁用进度条？ [英] How to disable the progress bar when using the nlfilter function in Matlab?

问题描述

每次调用 nlfilter 函数时，都会出现一个进度条窗口。我怎么能禁用那个窗口？有没有像 -q 这样的选项？

Each time I call the nlfilter function a progress bar window appears. How could I disable that window?. Is there an option like -q?

我正在按行处理图像并应用自定义函数，所以调用nlfilter函数时生成的窗口很烦，而且还会降低系统的性能。

I'm processing an image by rows and applying a custom function, so the window generated when calling to the nlfilter function is bothering quite a lot and also decreasing the performance of my system.

请注意，我只想暂时禁用窗口。

Note that I'm only want disable the window momentarily.

推荐答案

MATLAB中的 waitbar 肯定会降低代码的性能在某些操作系统上运行长时间运行的任务时，它会变得非常讨厌，因为它可以随机窃取键盘/鼠标的焦点。

The waitbar within MATLAB definitely reduces the performance of your code as well as gets really obnoxious when running long-running tasks on some operating systems as it can steal the focus of your keyboard/mouse randomly.

我个人创建自己的 waitbar 函数并将其放在MATLAB路径上，以便评估它而不是内置函数。

I personally create my own waitbar function and place it on the MATLAB path so that it is evaluated rather than the built-in.

我有一个更复杂的基于文本的进度条，但以下函数将简单地将消息打印到命令行。你甚至可以删除第一个块，内容只是 varargout = {[]}; ，你将没有输出。

I have a more complicated text-based progress bar, but the following function will simply print the messages to the command line. You could even remove the first block and have the contents simply be varargout = {[]}; and you will have no output.

function varargout = waitbar(varargin)
    if nargin >= 2 && ischar(varargin{2})
        disp(varargin{2})
    elseif nargin >= 3 && ischar(varargin{3})
        disp(varargin{3})
    end
    varargout = {[]};
end

请务必将此保存在 waitbar.m MATLAB路径上的某个位置。

Be sure to save this in waitbar.m somewhere high on your MATLAB path.

注意：这会使沉默所有等待栏，所以如果你想恢复典型的等待栏行为，你需要删除/重命名这个文件。

NOTE: This will silence all waitbars so if you want to restore the typical waitbar behavior, you will want to remove/rename this file.
