CELLDOT is the jCell module of jLab.

 CELLDOT  Dot product for arrays of column vectors.
 
    P=CELLDOT(X,Y), with X and Y being cell arrays of column vectors,
    returns a column vector P of length LENGTH(X), such that the nth 
    element of P is given by P(n)=SUM(X{n}.*CONJ(Y{n})).
 
    Note that this dot product is defined to conjugate the second input 
    argument, unlike Matlab's DOT which conjugates the first argument.
 
    P=CELLDOT(X,Y,'norm') normalizes the magnitude of dot product to be
    between zero and one.  This is done by dividing the nth element by
    SQRT(SUM(ABS(X{n}).^2).*SUM(ABS(Y{n}).^2)).
 
    CELLDOT uses 'omitnan' to exclude any NaNs from the summation.
 
    Usage: p=celldot(x,y);
           p=celldot(x,y,'norm');
