 Parameters:
 * `outputVariable`: denotes the shape and dynamic axes when copying data from this Value to the buffers.
 * `sequenceLength`: on return, it is set to the length of the sequence stored in the Value.
-* `colStarts`: on return, it contains indices into the `nonZeorValues` of the first non-zero element of each column of the matrix.
