getLVarMatForOneVec(x_vec, breaks = NULL, nbin.max = 100, only_info = FALSE)A list with the following fields:
breaks: Same as input
dummy_mat: The created L-variable matrix (only if only_info=FALSE).
A numeric vector representing original variable.
A numeric vector representing breaks of bins (If NULL, automatically generated).
