ArrayResample

ArrayResample[array,{n1,n2,}]
resamples array to have dimensions .

ArrayResample[array,dspec]
resamples array according to the dimension specification dspec.

ArrayResample[array,dspec,scheme]
specifies resampling scheme, either point or bin based.

ArrayResample[array,dspec,scheme,{{a1,b1},}]
resamples in the data sub range using the rest of array for padding if necessary.

Details and OptionsDetails and Options

  • ArrayResample can be used for resampling data arrays based on a large selection of interpolation and approximation models.
  • ArrayResample works with data arrays of any depth.
  • The dimension specification dspec can be of the form:
  • nn samples
    Scaled[s]rescale sampling resolution by factor s
    Allpreserve dimension
    Automaticpreserve dimension ratios
    {dspec1,,dspeck}resample up to the ^(th) dimension
  • For a multidimensional array, the notation n is taken to be equivalent to {n,Automatic,} and {n} equivalent to {n,All,}.
  • The dimension ratios for an array of dimensions is taken to be .
  • The scheme determines the location of sample and resample positions and can be of the form:
  • "Point"point sampling (default)
    "Bin"bin sampling
    {"Bin",alignment}bin sampling with specified alignment
  • For input data of length n the resampling scheme assumes a data range from 1 to n and the scheme assumes data range from to n with the alignment indicating the sample location within each bin.
  • The data range can be modified using the DataRange option.
  • Bin alignment alignment can be Left, Center, Right, or any number between -1 (Left) and 1 (Right).
  • Following options can be given:
  • DataRangeAutomaticrange of the input data
    Padding"Fixed"padding method
    ResamplingAutomaticresampling method
  • For possible settings for Padding, see the reference page for ArrayPad.
