How to use the inline function in MATLAB?

In MATLAB, the inline function is used to create embedded functions, with the following syntax:

f = inline(expr, var1, var2, ...)

‘expr’ represents the expression of the function, and ‘var1’, ‘var2’, … are the variables of the function. The nested functions can be called using ‘f’.

Here is an example:

f = inline('x^2 + x + 1', 'x');
result = f(2);  % 调用内嵌函数，并传入参数 2

The above code creates a nested function f that represents the function x^2 + x + 1. Afterwards, the function is called with result = f(2) by passing in the parameter 2, resulting in 7.
