Detailed Description
template<typename Scalar_ = double>
struct Tomographer::HistogramParams< Scalar_ >
The parameters of a Histogram.
This is the \([\text{min},\text{max}]\) range along with the number of bins.
- Since
- Since Tomographer 5.3, this class can be serialized with Boost.Serialization.

Member Function Documentation
§ binCenterValue()
|
inline |
Returns the value which a given bin index represents (center bin value)
This is the value at the center of the bin.
- Note
- The index must be valid, i.e.
index >= 0 && index < num_bins, or you might get anassert()failure in your face.
Definition at line 157 of file histogram.h.
§ binIndex()
|
inline |
Returns which bin this value should be counted in (index in the histogram's bins array)
- Note
- Raises std::out_of_range if the value is not in the range \( [\text{min},\text{max}[ \).
Definition at line 117 of file histogram.h.
§ binIndexUnsafe()
|
inline |
Returns which bin this value should be counted in.
This function blindly assumes its argument is within bounds, i.e. it must satisfy isWithinBounds(value).
Use this function only if you're sure the value is within bounds, otherwise call binIndex().
Definition at line 133 of file histogram.h.
§ binLowerValue()
|
inline |
Returns the value which a given bin index represents (lower bin value limit)
This is the value at the left edge of the bin.
- Note
- The index must be valid, i.e.
index >= 0 && index < num_bins, or you might get anassert()failure in your face.
Definition at line 145 of file histogram.h.
§ binResolution()
|
inline |
Returns the width of a bin.
This is simply (max - min) / num_bins.
Definition at line 179 of file histogram.h.
§ binUpperValue()
|
inline |
Returns the value which a given bin index represents (upper bin value limit)
This is the value at the right edge of the bin.
- Note
- The index must be valid, i.e.
index >= 0 && index < num_bins, or you might get anassert()failure in your face.
Definition at line 170 of file histogram.h.
§ isWithinBounds()
|
inline |
Tests whether the given value is in the range of the histogram.
- Returns
trueifvalueis finite (not inf or nan) and within the interval \([\text{min},\text{max}[\).
