## Define Documentation

#define ClpTraceDebug | ( | expression |  | ) |

      }

## Function Documentation

double maximumAbsElement | ( | const double * | region,
|  | int | size |
| ) |  |  |

Note (JJF) I have added some operations on arrays even though they may duplicate CoinDenseVector.

I think the use of templates was a mistake as I don't think inline generic code can take as much advantage of parallelism or machine architectures or memory hierarchies.

void setElements | ( | double * | region,
|  | int | size,
|  | double | value |
| ) |  |  |

void multiplyAdd | ( | const double * | region1,
|  | int | size,
|  | double | multiplier1,
|  | double * | region2,
|  | double | multiplier2 |
| ) |  |  |

double innerProduct | ( | const double * | region1,
|  | int | size,
|  | const double * | region2 |
| ) |  |  |

void getNorms | ( | const double * | region,
|  | int | size,
|  | double & | norm1,
|  | double & | norm2 |
| ) |  |  |

double CoinSqrt | ( | double | x | ) | `[inline]`

void ClpTracePrint | ( | std::string | fileName,

|  | int | line |
