WebInverse of a Matrix. We write A-1 instead of 1 A because we don't divide by a matrix! And there are other similarities: When we multiply a number by its reciprocal we get 1: 8 × 1 8 … Webmore. For any function f: X -> Y, the set Y is called the co-domain. The subset of elements in Y that are actually associated with an x in X is called the range of f. Since in this video, f is invertible, every element in Y has an associated x, so the range is actually equal to the co-domain. So yes, Y is the co-domain as well as the range of f ...
WebIn linear algebra, the trace of a square matrix A, denoted tr (A), [1] is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix ( n × n ). It can be proved that the trace of a matrix is the sum of its (complex) eigenvalues (counted with multiplicities).
