This text explores aspects of matrix theory that are most useful in developing and appraising computational methods for solving systems of linear equations and for finding characteristic roots. Suitable for advanced undergraduates and graduate students, it assumes an understanding of the general principles...
The second part is a new textbook by Strang. It provides examples, codes, and exercises to connect the theory of the Finite Element Method directly to the applications. The reader will learn how to assemble the stiffness matrix K and solve the finite element equations KU=F. Discontinuous ...
ON THE MATRIX EQUATION X+ A~*X~(-1)A = P : SOLUTION AND PERTURBATION ANALYSIS关于矩阵方程X+A~*X~(-1)A=P的解及其扰动分析 The Hermitian positive definite solutions of the matrix equation X+A*X-1A = P are studied, where A is an n×n nonsingular matrix and P is an n ×n Hermi...
This approach, however, does not really invert the forward CZT in the general case, i.e., for logarithmic spiral contours. This approach also doesn’t work for all chirp contours that lie on the unit circle, because the inverse of the Vandermonde matrix used by the forward transform is ...
Journal of Contemporary Mathematical Analysis is a peer-reviewed platform for research in the field of mathematical analysis. Originally based on contributions from a prolific group of mathematicians in Yerevan, Armenia, it carries on the traditions of that school. ...
