ST_MATMODE_INPLACE

The coefficient matrix of the linear system, \(A-\sigma B\), is built explicitly overwritting \(A\).

Note

This mode uses less memory than ST_MATMODE_COPY, but it modifies \(A\). This alteration of \(A\) is reversed after the eigensolution process has finished, but due to roundoff, the result might not be exactly equal to the original \(A\).
