CELLSPLIT is the jCell module of jLab.

 CELLSPLIT  Splits cell arrays of numeric arrays at data gaps.
 
    TO=CELLSPLIT(T,TOL), where T is a cell array of time arrays, splits T
    into additional cells wherever gaps of longer than duration TOL occur.
    Thus TO contains no gaps of longer than duration TOL. 
 
    TOL may either be a scalar or an array of length T.
 
    As an example, if T is a length two cell array 
    
        T{1}=[1 2 3 8 9 12 17]';  T{2} =[1 6 7]'; 
 
    then TO=CELLSPLIT(TI,3) leads to 
 
        TO{1}=[1 2 3]'; TO{2}=[8 9 12]'; TO{3}=17; TO{4}=1; TO{5}=[6 7]'; 
  
    such that there are no gaps in TO greater than 3. 
 
    In the process of this splitting, any empty cells in T are removed.  
 
    [TO,Y1,Y2,...,YN]=CELLSPLIT(T,X1,X2,...,XN,TOL) where the XN are cell
    arrays of the same size as T, splits the XN at the *same locations* at
    which T is split, and returns the results in the YN.  
 
    The purpose of this is to separate all variables XN into separate cells 
    whenever data gaps are longer than a specified cutoff.
    
    CELLSPLIT(T,X1,X2,...,XN,TOL); with no output arguments overwrites
    the original input variables T and X1,X2,...XN.
 
    'cellsplit --t' runs a test.
 
    Usage: to=cellsplit(t,tol);
           [to,y1,y2,y3]=cellsplit(t,x1,x2,x3,tol);
           cellsplit(t,x1,x2,x3,tol);
