Subject: [PATCH] Fix build errors in PR #11

- Fix SigGrad template function compilation error by using Diff(T(1), mat)
  instead of Diff<T>(1, mat) to properly cast the literal
- Fix printf format specifiers in matrix.cpp (%0.2l -> %ld, %0.2d -> %d, %0.2u -> %u)
- Remove invalid precision specifiers from integer format strings

These changes resolve the compilation errors that were preventing the PR build from succeeding.
