vb.net做矩阵运算,vb输出矩阵

求助！用Vb.net编写两个矩阵相乘！

Public Shared Sub Main()

Dim a As Integer, b As Integer, c As Integer, d As Integer

Console.WriteLine("该程序将求出两个矩阵的积:")

Console.WriteLine("请指定矩阵A的行数:")

a = Integer.Parse(Console.ReadLine())

Console.WriteLine("请指定矩阵A的列数:")

b = Integer.Parse(Console.ReadLine())

Dim MatrixA As Integer(,) = New Integer(a - 1, b - 1) {}

For i As Integer = 0 To a - 1

For j As Integer = 0 To b - 1

Console.WriteLine("请输入矩阵A第{0}行第{1}列的值:", i + 1, j + 1)

MatrixA(i, j) = Integer.Parse(Console.ReadLine())

Next

Next

Console.WriteLine("矩阵A输入完毕.")

Console.WriteLine("请指定矩阵B的行数:")

c = Integer.Parse(Console.ReadLine())

Console.WriteLine("请指定矩阵B的列数:")

d = Integer.Parse(Console.ReadLine())

Dim MatrixB As Integer(,) = New Integer(c - 1, d - 1) {}

For i As Integer = 0 To c - 1

For j As Integer = 0 To d - 1

Console.WriteLine("请输入矩阵A第{0}行第{1}列的值:", i + 1, j + 1)

MatrixB(i, j) = Integer.Parse(Console.ReadLine())

Next

Next

Console.WriteLine("矩阵B输入完毕.")

Console.WriteLine("矩阵A为:")

outputMatrix(MatrixA, a, b)

Console.WriteLine("矩阵B为:")

outputMatrix(MatrixB, c, d)

If b c Then

Console.WriteLine("矩阵A的列数与矩阵B的行数不相等,无法进行乘积运算!")

Return

Else

Console.WriteLine("矩阵A与矩阵B的乘积为:")

End If

Dim MatrixC As Integer(,) = New Integer(a - 1, d - 1) {}

For i As Integer = 0 To a - 1

For j As Integer = 0 To d - 1

MatrixC(i, j) = 0

For k As Integer = 0 To b - 1

MatrixC(i, j) += MatrixA(i, k) * MatrixB(k, j)

Next

Next

Next

outputMatrix(MatrixC, a, d)

End Sub

Private Shared Sub outputMatrix(MatrixX As Integer(,), rowCount As Integer, columnCount As Integer)

For i As Integer = 0 To rowCount - 1

For j As Integer = 0 To columnCount - 1

Console.Write(MatrixX(i, j) vbTab)

Next

Console.WriteLine()

Next

End Sub

End Class

Q1: vb.net中矩阵计算问题请教高手.

给你一个函数 Public Sub Vect1XtoVect2(ByVal x1 As Double, ByVal y1 As Double, ByVal z1 As Double, _ ByVal x2 As Double, ByVal y2 As Double, ByVal z2 As Double, _ ByRef xNew As Double, ByRef yNew As Double, ByRef zNew As Double) '矢量叉积 xNew = y1 * z2 - z1 * y2 yNew = z1 * x2 - x1 * z2 zNew = x1 * y2 - y1 * x2 End Sub其中x1,y1,z1为第一个矢量，x2,y2,z2为第二个矢量xnew,ynew,znew为得到的新矢量

Q2: 用vb.net编程，建立一个m行n列的矩阵，找出其中最小的元素所在的行和列，并输出该值及其行、列位置

没错!!

你的算法是：

1.定义三个变量，minValue（放最小值），X（放最小值的X坐标），Y（放最小值的Y坐标）。

2.遍历矩阵。在遍历过程中将最小值放在minValue中，最小值的X坐标放在X中，最小值的Y坐标放在X中。

Q3: VB.NET写了一个矩阵乘法的程序 代码如下

淳朴，古拙，淡泊，深远。闲居山林，逍遥河上，也许人只有摆脱了物欲的禁锢，才能让灵魂得到飞升。不识字烟波钓叟，傲杀人见万户侯；闲居山野的隐士，羞煞世上名利客。

斜风细雨，江南春色，落英缤纷。春水媚，绿波盈，青山横，白鹭飞。披蓑戴笠，心逐白云，意随鱼戏，行到水穷，坐看云起，卧听风韵松涛。不须归，不须归，只任心灵，放逐在深爱的自然里，忘世忘机。

《芥子园画谱》云：“与山水有顾盼，人似看山，山亦似俯而看人”。司空图《诗品冲淡》说：“遇之非深，即之逾稀。”空灵天真，非性情中人而不能为。梅妻鹤子友麋鹿，是怎样一种超逸？
