Examine the following MATLAB statements . Are they correct or incorrect ? color =' yellow '; switch ( color ) case ' red ', disp (' Stop now !'); case ' yellow ', disp (' Prepare to stop .'); case ' green ', disp (' Proceed through intersection .'); otherwise , disp (' Illegal color encountered .'); end disp (' Stop now !'); case ' yellow ', disp (' Prepare to stop .'); case ' green ', disp (' Proceed through intersection .'); otherwise , disp (' Illegal color encountered .'); end

The given MATLAB statements are incorrect. The 'disp (' Stop now !');' statement is outside the switch statement and does not have any case associated with it. It should be removed or placed inside a relevant case statement. The corrected code is shown below:

color = 'yellow';
switch (color)
    case 'red'
        disp('Stop now!');
    case 'yellow'
        disp('Prepare to stop.');
    case 'green'
        disp('Proceed through intersection.');
    otherwise
        disp('Illegal color encountered.');
end

Note that the 'otherwise' statement will execute if the input color does not match any of the defined cases.

Examine the following MATLAB statements . Are they correct or incorrect ? if volts >125 disp (' WARNING : High voltage on line .'); if volts <105 disp (' WARNING : Low voltage on line .'); else disp (' Line voltage is within tolerances .'); end 是否正确，中文解答，分析

这段 MATLAB 代码存在语法错误。正确的代码应该是：

if volts > 125
    disp('WARNING: High voltage on line.');
elseif volts < 105
    disp('WARNING: Low voltage on line.');
else
    disp('Line voltage is within tolerances.');
end

这段代码使用了 if-elseif-else 语句，首先判断 volts 是否大于 125，如果是则显示 "WARNING: High voltage on line."。如果 volts 不大于 125，则判断 volts 是否小于 105，如果是则显示 "WARNING: Low voltage on line."。如果 volts 既不大于 125，也不小于 105，则显示 "Line voltage is within tolerances."。

原始代码的问题在于，它没有使用 elseif 语句，而是在第一个 if 语句后面直接使用了一个 if 语句。这样的话，如果 volts 大于 125，第二个 if 语句还是会执行，导致程序出错。

树莓派Use dpkg --info (= dpkg-deb --info) to examine archive files.

The command "dpkg --info" (or "dpkg-deb --info") is used to examine package files in Debian-based Linux distributions, including Raspbian on the Raspberry Pi.

To use the command, you need to specify the package file name as an argument. For example, if you have a package file named "mypackage.deb" in your current directory, you can run the following command to examine its information:

dpkg --info mypackage.deb

This will display detailed information about the package, including its name, version, architecture, dependencies, and installed files.

You can also use the "dpkg-deb" command with the same syntax to achieve the same result:

dpkg-deb --info mypackage.deb
