[交流] 【求助】关于matcont symbolically选项的疑问 已有3人参与

请问matcont中关于这一栏是如何选择的呢,如下图所标
这下面英文应该是它的描述,可是看不懂怎么回事,哪位明白还请指点下,十分感谢
  The appearance of the System window depends on the presence of the Matlab
symbolic toolbox. If it is present, then we have the option to compute derivatives
of the object function by marking the dots in the line’symbolically’.If the Matlab
symbolic toolbox is not installed then the line ’symbolically’ is replaced by the
line ’from file’. This means that we can define derivatives by a file which may
have been generated by a symbolic package, e.g. Maple.
  We can also mark dots in the line ’from window’; this will open additional
windows where we can input explicit formulas for the derivatives of the object
function. If none of these options are chosen, then derivatives are computed
’numerically’, i.e. by finite differences
