Matlab:如何在 matlabFunction 中指定输入? [英] Matlab: How to specify input in matlabFunction?

问题描述

matlabFunction() 是一个可以将符号转换为匿名函数的函数.但是如何指定在匿名函数上出现哪些输入参数?

matlabFunction() is a function that can convert symbolic to anonymous function. But how to specify what input arguments to be appeared on the anonymous function?

例如

x = sym('x', [3, 1])
func = matlabFunction(x)

它返回一个句柄:

func =

  function_handle with value:

    @(x1,x2,x3)[x1;x2;x3]

但是如何让它返回:?

@(x) [x(1); x(2); x(3)]

整个 x 是输入参数，而不是它的每个元素.当 x 有很长的列时，这可能非常有用.

that the whole x is the input arguments, not every element of it. This could be extremely useful when x has very long colums.

推荐答案

你可以输入 x 的元素作为 逗号分隔列表 到 func 首先将 x 转换为元胞数组.

Instead of making that anonymous function, you can input the elements of x as a comma separated list to func by first converting x to a cell array.

xcell = num2cell(x);
func(xcell{:})
