Определить виды матриц из данного примера: (2*a*e)+t для vba, знаю только, что e-треугольная. sub sup() dim a() as integer dim b() as integer dim c() as integer dim d() as integer dim e() as integer dim t() as integer dim n as integer dim i as integer dim j as integer dim k as integer n = inputbox("введите количество столбцов") redim a(n, n) redim b(n, n) redim c(n, n) redim d(n, n) redim e(n, n) redim t(n, n) randomize range("a1").value = "(2*a*t)+e" range("a2").value = "матрица a" for i = 1 to n for j = 1 to n if i < > j then a(i, j) = 1 end if next j next i for i = 1 to n for j = 1 to n cells(2 + 1, j).value = a(i, j) next j next i cells(3 + n, 1).value = "матрица t" for i = 1 to n for j = 1 to n if i > = j then t(i, j) = 0 else t(i, j) = rnd * 10 end if next j next i for i = 1 to n for j = 1 to n cells(3 + n + i, j).value = t(i, j) next j next i cells(4 + n * 2, 1).value = "матрица e" for i = 1 to n for j = 1 to n e(i, j) = rnd * 10 if i < > j then e(j, i) = c(i, j) next j next i for i = 1 to n for j = 1 to n cells(4 + n * 2 + i, j).value = e(i, j) next j next i cells(5 + n * 3, 1).value = "c=a*t" for i = 1 to n for j = 1 to n e(i, j) = 0 for k = 1 to n e(i, j) = e(i, j) + a(i, k) * t(k, j) next k next j next i for i = 1 to n for j = 1 to n cells(5 + n * 3 + i, j).value = c(i, j) next j next i cells(6 + n * 4, 1).value = "b=c*2" for i = 1 to n for j = 1 to n b(i, j) = c(i, j) * 2 next j next i for i = 1 to n for j = 1 to n cells(6 + n * 4 + i, j).value = t(i, j) next j next i cells(7 + n * 5, 1).value = "d=b+c" for i = 1 to n for j = 1 to n d(i, j) = b(i, j) + c(i, j) next j next i for i = 1 to n for j = 1 to n cells(7 + n * 5 + i, j).value = d(i, j) next j next i end sub
