	)

inlinestatic

Shift the and scale the MxM symmetric matrix matrix.

Template Parameters

M	The size of the matrix.
FloatingPoint	A floating point type.

Parameters

matrix	The matrix to shift and scale.
shift	The amount the matrix is shifted.
maxEntryAfterShift	The amount the matrix is scaled by after the shift.

Note: The resulting matrix is guaranteed to have a zero trace and its entries will be in [-2, 2].; The size of matrix is SYM_SIZE< M >, but the intel compiler complains so the calculation must be inlined.
