In order to solve the linear algebraic system AX=b in complex domain, where A is a weakly cyclic of index p= 3 matrix (p-cyclic matrix), the convergence propert
We extend some fundamental concepts of qualitative matrix analysis from sign patternclasses of real matrices to sign pattern classes of nonreal matrlces.Given t
Let K be a proper cone in R~x,let A be an n×n real matrix that satisfies AK(?)K,letb be a given vector of K,and let λbe a given positive real number.The f
