I want to insert the equation
$$
X = \left[ {\matrix
{x_1 } \\ {x_2 } \\ {x_3 } \\ {x_4 } \\
\endmatrix } \right]\quad C = \left[ {\matrix {c_1 } \\ {c_2 } \\ {c_3 } \\ {c_4 } \\
\endmatrix } \right]\quad I = \left[ {\matrix 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \\
\endmatrix } \right]\;A = \left[ {\matrix {a_{11} } & {} & {} & {a_{14} } \\ {} & {} & {} & {} \\ {} & {} & {} & {} \\ {a_{41} } & {} & {} & {a_{44} } \\
\endmatrix } \right]
$$
but the software can't parse. dml 13:38, 9 Oct 2004 (UTC)
