This condition provides a new approach to choose the penalty param- eters adaptively for a fixed point iteration algorithm. Meanwhile, the result is extended to matrix completion which is a new field on the heel of the compressed sensing. The numerical experiments of sparse vector recovery and low-rank matrix completion show validity of the theoretic results.展开更多

Since 1980, when is was granted self-operational rights, the company has increased year by year in terms of export volume, with its management improving and economic returns steadily rising. In 1995, its import and export volume hit US$119.展开更多
