Line breaks in MATLAB strings
提问by Kristian
I am writing a code in which I am asking the user for an input. However the string informing the user about this is somewhat long, and when I use the code, it all gets written on a single line in the command window. I would like to have this spread over multiple lines. My code is:
我正在编写一个代码，我在其中要求用户输入。然而，通知用户这一点的字符串有点长，当我使用代码时，所有这些都写在命令窗口的一行中。我想让它分布在多条线上。我的代码是：
n = input(['The matrix is diagonally dominant. Please choose which method you wish to'...
' use: 1 (Gaussian elimination), 2 (Jacobi iterations),'...
' 3 (Gauss-Seidel iterations). If you enter any other number'...
' Gaussian elimination will automatically be used: ']);
If preferable, I would like to have this displayed over 4 lines, as in the code. How can I go about getting this done?
如果愿意，我希望将其显示在 4 行以上，如代码中所示。我怎样才能完成这件事？

use sprinf and \n (newline character)
使用 sprinf 和 \n（换行符）
n = input(sprintf(['The matrix is diagonally dominant. Please choose which method you wish to\n'...
' use: 1 (Gaussian elimination), 2 (Jacobi iterations),\n'...
' 3 (Gauss-Seidel iterations). If you enter any other number\n'...
' Gaussian elimination will automatically be used: ']));

Use \nas an break character, for example:
使用\n作为间隔字符，例如：
n = input(sprintf('blablabla\nblablabla\n'))
