arguments: A:SparseMutableMatrix LLLstate:SparseMutableMatrix nsteps:int >> int
Compute the LLL reduction of the matrix A, using the state setup originally by ggLLLinit. Compute 'nsteps' amount. If this is -1, compute until done, or interrupted. See the documentation for ggLLLinit for more information. Return values: if an error: -2 (e.g. the columns of 'A' are not independent), if completely done: 0, if interrupted: -1, if done with the given number of steps, but not completely done: 9.
