 TimeStats (const int newCount, const double newMin, const double newMax, const double newMean, const double newTotal)

Detailed Description

Collect running statistics.

TimeStats collects running statistics on a particular timing, which is collected count() times. When you get a new timing, call update().

Constructor & Destructor Documentation

TSQR::TimeStats::TimeStats ( const int  newCount,
const double  newMin,
const double  newMax,
const double  newMean,
const double  newTotal 
) [inline]

Construct a TimeStats object from its constituent data. This is useful for computing global statistics over many MPI processes, or for otherwise combining different TimeStats objects.

Note:
This design is suboptimal, because it makes it hard for new statistics to be added to the class.

Member Function Documentation

void TSQR::TimeStats::init ( )

Reset the statistics

Definition at line 12 of file Tsqr_TimeStats.cpp.

void TSQR::TimeStats::update ( const double  curTime)

Add a new data point and update the running statistics

Definition at line 21 of file Tsqr_TimeStats.cpp.

void TSQR::TimeStats::print ( std::ostream &  out,
const bool  humanReadable,
const std::string &  label,
const std::string &  labelLabel,
const bool  printHeaders 
) const

Print to out

Parameters:
out[in/out] Output stream to which to print
humanReadable[in] Whether to print in a format easy for humans to read, or easy for automatic parsing
label[in] If not humanReadable, then print this string as a row identifier at the beginning of the row
labelLabel[in] If not humanReadable, then use this as the column header for the "label" (first) column
printHeaders[in] If not humanReadable, then print column headers, preceded by a "%" so that the parser will ignore the line
