%X Donoho D L and Elad M proved stability theorem of problem (*P*_{0}^{ε}) by using the properties of matrix's mutual-coherence and spark_{η}(*A*) respectively. Counter-example was used to show that there were some mistakes in Elad M's proof, and then stability theorem of problem (*P*_{0}^{ε}) was reproved by using the properties of spark_{η}(*A*) and the singular value of matrix.
