在MATLAB中静默警告消息 [英] Silencing warning messages in MATLAB

问题描述

有时，当我致电 <在MATLAB中c0> 将2D图像添加到视频中，我收到以下警告消息.

Sometimes, depending on the size of an image, when I call addframe in MATLAB to add 2D images to a video, I get the following warning message.

警告:框架高度已被填充为四的倍数，例如 指定编解码器所需. 在127的avifile.addframe中

Warning: The frame height has been padded to be a multiple of four as required by the specified codec. In avifile.addframe at 127

我的问题是:

1. 有没有办法像这样使特定警告静音?如果是这样，是否有可能在我的代码的变量中捕获警告(即类似于try& catch异常机制)，而不是让MATLAB在命令窗口中打印此警告?

1. Are there any ways of silencing specific warnings like this? If so, is it possible to capture a warning in a variable in my code (i.e. similar to the try & catch exception mechanism) rather than having MATLAB print this warning in the command window?

如果以上都不可行.是否可以通过暂时使所有警告静默?

If the above is not possible. Is it there a way to silence all warnings in MATLAB temporarily?

推荐答案

使用warning命令，您可以按ID静默所有警告或特定警告:

Using the warning command, you can silence either all warnings or specific warnings by ID:

WARNING('OFF', 'MSGID')和WARNING('ON', 'MSGID')禁用并启用 显示带有消息标识符MSGID的任何警告. (使用LASTWARN 确定警告的标识符，或使用WARNING VERBOSE功能 如下所述.)WARNING在匹配消息时不区分大小写 标识符.

WARNING('OFF', 'MSGID') and WARNING('ON', 'MSGID') disable and enable the display of any warning tagged with message identifier MSGID. (Use LASTWARN to determine the identifier of a warning, or use the WARNING VERBOSE feature described below.) WARNING is not case sensitive when matching message identifiers.
