matlablegend分为两列

您可以使用Matlab中的'NumColumns'属性来指定图例分为两列显示。在您的代码中，只需将'NumColumns'的值设置为2即可。下面是修改后的代码示例：

legend({'2.2 mVrms (\itm\rm =4.6 dB)','3.1 mVrms (\itm\rm = 7.5 dB)',..., '4.4 mVrms (\itm\rm = 10.6 dB)','6.9 mVrms (\itm\rm = 14.5 dB)',..., '16 mVrms (\itm\rm = 21.8 dB)','200 mVrms (\itm\rm = 43.7 dB)',..., 'No AGC (DD)'},'Fontsize',10,'Location','southeast',...
 'NumColumnsMode','manual','NumColumns',2)

这样，图例将会分为两列进行显示。希望这个回答对您有帮助！<span class="em">1</span><span class="em">2</span><span class="em">3</span>
