1-D detail coefficients

returns a cell array containing the detail coefficients. A minimum of two levels
must be specified. The `D`

= detcoef(`C`

,`L`

,`N`

,'cells')*i*^{th} element
of `D`

contains the detail coefficients at the
*i*^{th} specified level.

If

`length(N)>1`

, the`D = detcoef(C,L,N)`

is equivalent to`D = detcoef(C,L,N,'cells')`

.`D = detcoef(C,L,'cells')`

is equivalent to`D = detcoef(C,L,[1:NMAX])`

, where`NMAX = length(L)-2`
