Keywords: | P-matrix; P-problem; Sign-real spectral radius | Issue Date: | 10-Jan-2002 | Publisher: | American Elsevier Publ. | Source: | Linear Algebra and Its Applications (363): 237-250 (2003-04-01) | Abstract (english): | We present some necessary and sufficient conditions for a real matrix to be a P-matrix. They are based on the sign-real spectral radius and regularity of a certain interval matrix. We show that no minor can be left out when checking for P-property. Furthermore, a not necessarily exponential method for checking the P-property is given. |
