createMultichannelSource

Arguments

:: Storable a 
=> Int

sampling rate

-> Int

bits of precision

-> [Vector a]

data

-> Multichannel a

datatype

create a multichannel data type

sampling_rate :: Multichannel a -> IntSource

the sampling rate

precision :: Multichannel a -> IntSource

the bits of precision

channels :: Multichannel a -> IntSource

the number of channels

samples :: Multichannel a -> IntSource

the length, in samples

detrended :: Multichannel a -> BoolSource

was the data detrended?

filtered :: Multichannel a -> Maybe (Int, Int)Source

was the data filtered?

getChannel :: Int -> Multichannel a -> Vector aSource

extract one channel

getChannels :: Multichannel a -> Array Int (Vector a)Source

extract all channels

toMatrix :: Element a => Multichannel a -> Matrix aSource

convert the data to a matrix with channels as rows

mapConcurrentlySource

Arguments

:: Storable b 
=> (Vector a -> Vector b)

the function to be mapped

-> Multichannel a

input data

-> Multichannel b

output data

map a function executed concurrently

detrend :: Int -> Multichannel Double -> Multichannel DoubleSource

detrend the data with a specified window size

filter :: (Filterable a, Double ~ DoubleOf a, Container Vector (Complex a), Convert (Complex a)) => (Int, Int) -> Multichannel a -> Multichannel aSource

filter the data with the given passband

sliceSource

Arguments
