I would like to compute correlation matrices (using CORRELATE) for each group in a worksheet. The correlation matrices should be by group (5,6,7,12,13, or 14) on columns D - H. Ideally the new sheet would be named with at least the group number.
Sub MakeMatrix()
Dim arr() As Long
Dim CurrentGroup As Long
Dim SourceWs As Worksheet
Dim LastR As Long
Dim Counter As Long
Dim DestWs As Worksheet
Set SourceWs = ThisWorkbook.Worksheets("data")
With SourceWs
.[a1].Sort Key1:=.[a1], Order1:=xlAscending, Header:=xlYes
LastR = .Cells(.Rows.Count, 1).End(xlUp).Row
CurrentGroup = .Cells(2, 1)
ReDim arr(1 To 3, 1 To 1) As Long
arr(1, 1) = CurrentGroup
arr(2, 1) = 2
For Counter = 3 To LastR
If .Cells(Counter, 1) <> CurrentGroup Then
arr(3, UBound(arr, 2)) = Counter - 1
ReDim Preserve arr(1 To 3, 1 To 1 + UBound(arr, 2)) As Long
arr(1, UBound(arr, 2)) = .Cells(Counter, 1)
arr(2, UBound(arr, 2)) = Counter
CurrentGroup = .Cells(Counter, 1)
ElseIf Counter = LastR Then
arr(3, UBound(arr, 2)) = Counter
End If
Next
End With
For Counter = 1 To UBound(arr, 2)
Set DestWs = ThisWorkbook.Worksheets.Add
With DestWs
.Name = "Group " & arr(1, Counter) & " Matrix"
.[a2:a6] = Application.Transpose(SourceWs.[d1:h1])
.[b1:f1].Value = SourceWs.[d1:h1].Value
.Range("b2, c3, d4, e5, f6") = 1
.[b3].Formula = "=CORREL(Data!D" & arr(2, Counter) & ":D" & arr(3, Counter) & _
",Data!E" & arr(2, Counter) & ":E" & arr(3, Counter) & ")"
.[b4].Formula = "=CORREL(Data!D" & arr(2, Counter) & ":D" & arr(3, Counter) & _
",Data!F" & arr(2, Counter) & ":F" & arr(3, Counter) & ")"
.[b5].Formula = "=CORREL(Data!D" & arr(2, Counter) & ":D" & arr(3, Counter) & _
",Data!G" & arr(2, Counter) & ":G" & arr(3, Counter) & ")"
.[b6].Formula = "=CORREL(Data!D" & arr(2, Counter) & ":D" & arr(3, Counter) & _
",Data!H" & arr(2, Counter) & ":H" & arr(3, Counter) & ")"

.[c5].Formula = "=CORREL(Data!E" & arr(2, Counter) & ":E" & arr(3, Counter) & _
",Data!G" & arr(2, Counter) & ":G" & arr(3, Counter) & ")"
.[c6].Formula = "=CORREL(Data!E" & arr(2, Counter) & ":E" & arr(3, Counter) & _
",Data!H" & arr(2, Counter) & ":H" & arr(3, Counter) & ")"
.[d5].Formula = "=CORREL(Data!F" & arr(2, Counter) & ":F" & arr(3, Counter) & _
",Data!G" & arr(2, Counter) & ":G" & arr(3, Counter) & ")"
.[d6].Formula = "=CORREL(Data!F" & arr(2, Counter) & ":F" & arr(3, Counter) & _

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.

The selection will be an array of column headers: dim columnNames() as string.
So if you select AREA1, AREA2, and SAREA5, you want the CORREL matrix based on that 3 x 3, correct?
Should not take long.
