Example 5: Finding the Sum and Difference of Two 3 x 3 Matrices Given AA and B:B: Find the sum. Find the difference. A=⎡⎢⎣2−10−21412104−22⎤⎥⎦ and B=⎡⎢⎣610−20−12−4−52−2⎤⎥⎦A=[2−10−21412104−22] and B=[610−20...
This is a lecture note of my joint work with Chi-Kwong Li concerning various results on the norm structure of n × n matrices (as Hilbert-space operators). The main result says that the triangle inequality serves as the ultimate norm estimate for the upper bounds of summation of two matric...

If you slice A along the first dimension, you can sum the elements of the resulting 4 pages, which are each 3-by-2 matrices. Get S2 = sum(A,[2 3]) S2 = 4×1 6 6 6 6 Slicing along the second dimension, each page sum is over a 4-by-2 matrix. Get S3 = sum(A,[1...
Since both pages are a 4-by-3 matrix of ones, the sum of each page is 12. Get S1 = sum(A,[1 2]) S1 = S1(:,:,1) = 12 S1(:,:,2) = 12 If you slice A along the first dimension, you can sum the elements of the resulting 4 pages, which are each 3-by-2 matrices...

As a corollary, we obtain an upper bound for the absolute value of the determinant of the sum of two normal matrices with specified eigenvalues. This corollary supports the determinantal conjecture of Marcus and de Oliveira. DOI: 10.1016/0024-3795(94)90356-5 被引量: 5 年份: 1994 ...
