环境：MacBook Air M1, macOS Monterey 12.6 安装 建议选择homebrew安装，安装完成后会显示基本信息，后续如果要重新查看可通过命令实现。 brew install nginx 安装 brew info nginx 查看信息 Docroot is: /opt/homebrew/var/www The default port has been set in /opt/homebrew/etc/nginx/nginx.conf to 8080 so that nginx can run without sudo. nginx will load all files in /opt/homebrew/etc/nginx/servers/. To restart nginx after an upgrade: brew services restart nginx Or, if you don't want/need a background service you can just run: /opt/homebrew/opt/nginx/bin/nginx -g daemon off; 使用 brew services start nginx 启动 brew services stop nginx 停止 nginx -t 测试配置文件 ...

cell 定义空cell 定义一个2✖️3的元胞结构数组 >> x=cell(2,3) x = 2×3 cell 数组 {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} cell读取时{}()的区别 ()读取得到的是元包结构，即cell数组 {}读取得到的是数据本身的内容，例如字符串 % 这个例子 >> title={{'pitch-RAO'} {'T'} {'heave-波能俘获效率'} } title = 1×3 cell 数组 {1×1 cell} {1×1 cell} {1×1 cell} >> title(1) ans = 1×1 cell 数组 {1×1 cell} >> title{1} ans = 1×1 cell 数组 {'pitch-RAO'} >> title(1)(1) 错误: 无效的数组索引。 >> title(1){1} 错误: 无效的数组索引。 >> title{1}{1} ans = 'pitch-RAO' >> title{1}(1) ans = 1×1 cell 数组 {'pitch-RAO'} 坐标轴科学记数法表示与轴范围的影响 xlim([xmin xmax]) x轴显示范围 ylim([ymin ymax]) y轴显示范围 xticklabel xtick x坐标轴标签 yticklabel ytick x坐标轴标签 ...
