It takes function handle ‘f’ and independent variable ‘x’ as arguments, and returns the numerical derivative of ‘f’ at ‘x’. Numerical differentiation functions can get much more elaborate. See for example the Wikipedia article on Numerical differentiation (link). John D'Errico 2019...
用法 v = get(key) 说明 v = get(key)返回指定键对应的VariableInstance。请注意,使用 MATLAB 的索引运算符(圆括号)可以实现相同的效果。 输入参数 要查找的变量实例的键。 输出参数 v 指定的变量实例 示例 创建一个索引变量,为每个变量获取一个实例,并将它们修复为某个值 ampl.eval('var x{1..5}; var...
