vb.net矩阵运算 vb计算矩阵

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:", i1, j1)
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:", i1, j1)
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 bc 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
【vb.net矩阵运算 vb计算矩阵】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
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vb.net矩阵运算,minValue(放最小值)vb.net矩阵运算,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 。
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
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?
vb.net 矩阵的运算控件有吗给vb.net矩阵运算你一个函数 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vb.net矩阵运算,x2,y2,z2为第二个矢量xnew,ynew,znew为得到
求助,初学者想问VB.NET , 怎么输入一维列矩阵或者一维行矩阵怎么转置成一维列矩阵?谢谢了!在程序设计语言里vb.net矩阵运算,用二维数组来保存矩阵的值 。
一维列矩阵vb.net矩阵运算,就是由vb.net矩阵运算:若干行、一列组成的二维数组 。
一维行矩阵,就是由:一行、若干列组成的二维数组 。
比如一维列矩阵 , 的输入:
dima(10,1) as integer'10行,1列
dim i as integer
for i = 1 to 10
a(i,1) = inputbox("")
next i
