返回一个指针的指针的函数 [英] Return a pointer to pointers in a function

问题描述

我有一个类的矩阵。该汇总表dinamically分配，我想封装它。

I have a matrix in one class. That matrix is allocated dinamically, I want to encapsulate it.

下面是在头文件我的矩阵声明：

Here is my matrix declaration in the Header file:

float** matrix;

这里是GET方法的声明：

And here is the declaration of get method:

float *getMatrix();

一切都正确为止？

Is everything correct so far?

我不知道如何在这种情况下，工作的指针。如何将get函数是什么样子？

I don't know how to work with pointers in that case. How would the get function look like?

推荐答案

如果你只想回到你应该使用矩阵

if you want just to return matrix you should use

float** getMatrix();
