Specify the -e option and provide an expression to evaluate. Again, wrap the expression in quotation marks to prevent interpolation by the shell.
指定- e选项并提供要运算的表达式。
We put a template expression within the interpolation braces when we wrote {{1 + 1}}.
当我们写{{1 + 1}}时，是往插值表达式的括号中放进了一个模板表达式。
Engineering applications, the interpolation and regression (curve fitting) function expression usually are used to describe data to solve the problem.
工程应用中通常用插值和回归(曲线拟合)解决函数表达式描述数据的问题。
Because the expression has an adjustable parameter, the interpolation curve has more flexibility.
由于表达式中含有调节参数，这使得插值曲线更具灵活性。
