The trace (tr) of a matrix is defined as the sum of the elements along the leading diagonal.Let A=(pmatrix) a&b c&d(pmatrix) and B=(pmatrix) e&f g&h(pmatrix) Show that (tr)(AB)=(tr)(BA) 相关知识点: 试题来源: 解析 AB=(pmatrix) ae+bg&af+bh ce+dg&cf+dh(pmatrix) ...
i got it now; the prof also wants to convert a non-square matrix to a square matrix and then find the halfsum. 추가 답변 (0개) 웹사이트 선택 번역된 콘텐츠를 보고 지역별 이벤트와 혜택을 ...
The trace (tr) of a matrix is defined as the sum of the elements along the leading diagonal. Let =(pmatrix) a&b c&(pmatrix) and =(pmatrix) e&f &h(pmatrix) .Hence prove that, if there exists a non-singular matrix such that P^(-1) (MP)=(pmatrix) p&0 0&q(pmatrix) the...

This is why Python'ssumfunctionhas an optional "start" argument: so you can initialize it with a "zero object" of the kind you are adding. In this case, with a zero matrix. >>>print(sum(ls, sp.zeros(2))) Matrix([[9,0], [0,9]]) ...
