Question: I have a function which returns an nxk matrix. Suppose I wanted to take each column of the matrix into a different variable, is there a one line way I can do this?

Currently I am doing (for k=3)

```
A = MyFunc(...);
x1 = A(:, 1);
x2 = A(:, 2);
x3 = A(:, 3);

```

I notice that doing

```
[x1, x2, x3] = MyFunc(...);

```

does not work but is there anything similar to this?

Answer: 
NDK is just a set of libraries and binary tools. 

Normally, you do not need to "uninstall" it. 

To "remove" it, you can:

* delete the ndk folder
* remove NDK environnent variable you have set previously
I am using Android Studio 3.5.3 and could remove or uninstall the obsolete NDK following the procedure listed below:

1. Use Tools->SDK Manager.
2. Go to the "SDK Tools" page in the "Android SDK" menu. REMEMBER to check the checkbox "Show Package Details" at the lower right corner.
3. You'll see all the NDK's you had installed, Un-check the NDK you'd like to uninstall and click "OK" at the bottom right to uninstall the selected NDK
