How can you define a four vector in mathcad?(adsbygoogle = window.adsbygoogle || []).push({});

Bascially, I want to adjust the vector (mutiplying by arbitary constants if necessary):

[tex]I = \left(\begin{array}{c}cdt\\dx\\dy\\dz\end{array}\right)[/tex]

such that:

[tex]|I|^2 = c^2dt^2 - dx^2 - dy^2 - dz^2[/tex]
