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,用二维数组来保存矩阵的值。
一维列矩阵,就是由: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:
dim a(10,1) as integer '10行,1列
dim i as integer
for i = 1 to 10
a(i,1) = inputbox("")
next i
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。
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 数组显示矩阵的一道题
'这是在vb6中的代码,在vb.net中基本差不多,你可以参考一下
Private Sub cmdCommand1_Click()
Me.AutoRedraw = True
Dim Grp
Grp = Array(1, 2, 3, 4, 5)
Dim i, j As Long
Dim StrPrt As String
For i = 0 To UBound(Grp)
'i为位移量
StrPrt = ""
For j = i To UBound(Grp)
StrPrt = StrPrt Grp(j)
Next j
For j = 0 To i - 1
StrPrt = StrPrt Grp(j)
Next j
Me.Print StrPrt
Next i
End Sub
