modEntryColumnOperation()

static void modEntryColumnOperation ( Matrix< DynamicAPInt > &  m, unsigned  row, unsigned  sourceCol, unsigned  targetCol, Matrix< DynamicAPInt > &  otherMatrix  )

static

Set M(row, targetCol) to its remainder on division by M(row, sourceCol) by subtracting from column targetCol an appropriate integer multiple of sourceCol.

This brings M(row, targetCol) to the range [0, M(row, sourceCol)). Apply the same column operation to otherMatrix, with the same integer multiple.
