Member Function Documentation

static Column ColumnOp::applyGain ( const Column &  in,
double  gain 
)
inlinestatic

Scale the given column using the given gain multiplier.

Definition at line 61 of file ColumnOp.h.

static Column ColumnOp::applyShift ( const Column &  in,
float  offset 
)
inlinestatic

Shift the values in the given column by the given offset.

Definition at line 72 of file ColumnOp.h.

ColumnOp::Column ColumnOp::fftScale ( const Column &  in,
int  fftSize 
)
static

Scale an FFT output downward by half the FFT size.

Definition at line 27 of file ColumnOp.cpp.

static bool ColumnOp::isPeak ( const Column &  in,
int  ix 
)
inlinestatic

Determine whether an index points to a local peak.

Definition at line 88 of file ColumnOp.h.

ColumnOp::Column ColumnOp::peakPick ( const Column &  in)
static

Return a column containing only the local peak values (all others zero).

Definition at line 33 of file ColumnOp.cpp.

References in_range_for().

ColumnOp::Column ColumnOp::normalize ( const Column &  in,
ColumnNormalization  n 
)
static

Return a column normalized from the input column according to the given normalization scheme.

Note that the sum or max (as appropriate) used for normalisation will be calculated from the absolute values of the column elements, should any of them be negative.

ColumnOp::Column ColumnOp::distribute ( const Column &  in,
int  h,
const std::vector< double > &  binfory,
int  minbin,
bool  interpolate 
)
static

Distribute the given column into a target vector of a different size, optionally using linear interpolation.

The binfory vector contains a mapping from y coordinate (i.e. index into the target vector) to bin (i.e. index into the source column). The source column ("in") may be a partial column; it's assumed to contain enough bins to span the destination range, starting with the bin of index minbin.
