Matrix

4. combination if A1,A2…Ak are m*n matrices and C1,C2…Ck are real numbers, then:
6. an m*n … is a rectangular array of a real numbers arranged in m-horizontal rows and n-vertical columns.
7. a square matrix for which every time of the main diagonal is zero.
8. the effect of the matrix transportation f with respect to X-axis in R^2.
10. there is a … m*n matrix 0 such that: A+O=A.
11. product is the sum of the product of corresponding entries.
12. leading nonzero entry in a row is to the right of the leading nonzero entry in the preceding row.

1. a matrix … is a function f:R^n=R^m defined by:f(u)=A*U
2. if A=[aij] is an m*p matrix and B=[bij] is a p*n matrix then the product of A and B is the m*n matrix C=[cij] defined by: cij=ai1bi1+ai2bi2+…+aipbpj=p k=1 aikbkj
3. echelon form all zero rows are at the bottom of the matrix.
5. a diagonal matrix for which all terms on the main diagonal are equal.
9. if A=[aij] is a m*n matrix then the … of A is denoted by A^t=[aij^t]is in the form of n*m.
