WebFor a matrix A, its inverse is A -1, and A · A -1 = A -1 · A = I, where I is the identity matrix. The matrix whose determinant is non-zero and for which the inverse matrix can be calculated is called an invertible matrix. For example, the inverse of A = ⎡ ⎢⎣1 −1 0 2⎤ ⎥⎦ [ 1 − 1 0 2] is ⎡ ⎢⎣1 1/2 0 1/2 ⎤ ⎥⎦ [ 1 1 / 2 0 1 / 2] as

WebDec 2, 2024 · I am generating this 1000x1000 real matrix A that is nonsingular. Linear algebra claims that det (A) = det (A') and that det (AA') = det (A'A) = det (A)det (A'). So if A is nonsingular, so are A' and A'A. Therefore if rank (A) = 1000 (full rank), then rank (A') = 1000 and rank (A'A) = 1000. Yet: Theme rank (A) ans = Theme 1000 >> rank (A') ans = size of stars youtube
