Description

It would be convenient to implement the matrix logarithm for small SMatrix values (e.g. 2x2, 3x3). This could be significantly faster than converting to Matrix first.

Research direction

Start by locating the matrix-function entry points for small SMatrix values and the existing Matrix conversion path. Compare how logarithms are handled after conversion, then define the supported 2x2 and 3x3 cases and verify that the direct implementation is faster while preserving expected results.
