iFit/pack

PURPOSE

SYNOPSIS

DESCRIPTION

 b = pack(a) : compress iData storage to save memory

   @iData/pack function to save memory when storing data sets
   This includes to compare sparse/full storage for large matrices, and
   reduce the Command history. Only the Signal, aliases and Axes are kept
   so that unused Data items are removed.
   In addition, to further 'clean' an object, use: fill(a) and squeeze(a)

 input:  s: object or array (iData)
 output: f: compressed object or array (iData)
 ex:     b=pack(a);

• find d = find(s) : find iData signal non zeros values
• findfield [match, types, nelements]=findfield(iData, field, option) : look for iData fields
• full b = full(s) : Convert iData object storage to full matrix
• get [...] = get(s, 'PropertyName', ...) : get iData object properties
• getalias [link, label,names] = getalias(s, 'AliasName') : get iData alias
• getaxis [val, lab] = getaxis(s, AxisIndex) : get iData axis value and label
• iData d = iData(a, ...) : iData class object constructor
