Solved: find max in multi dimensional array

[amateur1902]

Hello everyone,

what i would like to know is how can i find the max in a multidimensional array. I would like to search in vba and only the outcome has to be put in excell.

I use the following array.

i,0,0,1

i is a variable and place where i should find the max.

I really have no idea what i should do to make this work.

Thanks

This is for a 0-based variant array. The 'place' where we should find the max is supposed to be of type integer. You may change some things as they suit you.
Sub FindMaxInMultiDimArray()
Dim mult(0 to x, 0 to 0, 0 to 0, 0 to 1) as variant 'supply the x. It is the highest first dimension
Dim max As Integer, arr() As Integer
Dim i As Long, j As Byte, k As Long
For i = 0 To UBound(mult,1)
For j = 0 To 1
If k = 0 Then
ReDim arr(0 To k)
Else
ReDim Preserve arr(0 To k)
End If
arr(k) = mult(i, 0, 0, j)
k = k + 1
Next 'j
Next 'i
max = WorksheetFunction.Max(arr)

Range("A1").value = max
End Sub

Interpreting your OP differently, I might skip the For j loop.
Sub FindMaxInMultiDimArray()
Dim mult(0 To x, 0 To 0, 0 To 0, 0 To 1) As Variant 'supply the x. It is the highest first dimension
Dim max As Integer, arr() As Integer
Dim i As Long, k As Long
For i = 0 To UBound(mult, 1)
If k = 0 Then
ReDim arr(0 To k)
Else
ReDim Preserve arr(0 To k)
End If
arr(k) = mult(i, 0, 0, 1)
k = k + 1
Next 'i
max = WorksheetFunction.max(arr)

Range("A1").Value = max
End Sub

hi tstav,

again thanks for youre help. i am comming close with getting it right.
Except that i don't seem to get the array that i want in the proces.

The array that i have is the following:

vtresult(i, a, 0, 1)

In i i want to find the max and when i have found it i want to go to next array a. Then it starts all over again.

So when i've got 5 kind of rows in a. then i want to find the max for every row.

I hope it is clear.

Thanks

What am i doing wrong here? I tried in many ways to resolve my problem but i keep getting errors. For example expected expression for k. Why is that. Folowing i've got the whole code. But the problem you can find at max.(at the end of the code.)

If you have questions feel free to ask. I hope there is someone who can help me.

Not clear to me, amateur. I hope it is to someone else.

ill try to make it clear.

I've got a array, In this array there are multiple rows with figures.

From each row i want to find the max and put them in excell.

So when i've got 10 rows of figures in the array, then i want 10x max.

This is the array that i've got.

vtresult(i, a, 0, 1)

When i want to find max in 1 of the rows then i have to search trough i. so i believe this will look like this at the end of a loop i = 1 + i.

When i have found de max of the first row then i want to find it of the second row. To go to the second row i have to raise a. so a = a + 1. When i raise a with one then i'll get a new row with figures. Then from this row i want to find the max. and so on.

i think this will make it clear to you all.
