format可以设置command window output display,一般是设置小数点后几位输出以及设置输出的数进制 用法 控制输出精度 控制输出数进制 format可选参数 控制输出精度 比如下图: 不管输出format如何设置,在工作空间的value仍然是十进制,而且保持一定精度。 控制输出数进制 用16进制输出最大的64位数和32位数(10进制)。format...
You can change the display in the Command Window or Editor using theformatfunction. formatlongx x = 1.333333333333333 Using theformatfunction only sets the format for the current MATLAB session. To set the format for subsequent sessions, clickPreferenceson theHometab in theEnvironmentsection. Select...
