# Matrices and notation

Hi

I have a question regarding notation of matrices. I am trying to conserve space in my report, so instead of writing my matrix fully like this
$$\left( {\begin{array}{*{20}c} 1 & 2 \\ 0 & { - 5} \\ \end{array} } \right)$$
my plan is to write it as $(1,0 ; 2 -5)^T$. Is this notation correct? I must admit that I have not seen it being used before, and there might be a good reason for that.

Thanks for the help in advance.

Best,
Niles.

No, it isn't. Why would it be so important to save space?
