Octave：将矩阵导出到文件
Octave: exporting a matrix to a file
我猜对此有一个简单的解决方案，但我主要使用 Octave 交互式地求解方程组 online。问题是我当前问题的输出太大而无法轻松复制（手动或使用 copy/paste 复制到另一个文件），而且我不确定如何导出它。文本、LaTeX、.csv 或什至其他格式都可以，但导出它似乎很有用。
问题是屏幕打断了输出，因此很难 read/copy 没有错误。下面的代码（矩阵 C 是我想要导出的）：
syms a b c q r s t x
A = [ 1 , -x*a, -x*(1-a); -x*b, 1, -x*(1-b); -x*c, -x*(1-c), 1]
Ainv = inv(A)
B = [t + q; t+ r; t+s]
C = Ainv*B
我试过保存命令，但它似乎没有做任何我能说的事情。例如：save temp.txt, C 只是重述了命令，但似乎没有指示保存到我的计算机（甚至没有机会执行 so/ask 权限以将其保存在某个地方）。
感谢任何帮助。谢谢！
有@sym/latex所以很容易得到latex:
