Try the macro below...
It assumes your data starts at A1... i.e. Cells(i,j) with i=1, k=1
it writes out the values at A25 i.e. Cells(l,k) with l=25, k=1
You may change these values as per your requirment
It works on the activesheet

Sub deleteBlanks()
With ActiveSheet
l = 25
K = 1
For i = 1 To 20
For j = 1 To 20
If .Cells(i, j) < "" Then
.Cells(l, K) = .Cells(i, j)
If K = 20 Then
K = 1
l = l + 1
Else
K = K + 1
End If
End If
Next j
Next i
End With
End Sub

Hi, I have a 20x20 matrix of either non-zero values or "blanks" ("") that are
not constants--these cells have formulas.

I'd appreciate some assistance creating a macro that will systematically
traverse the matrix and delete cells (moving remaining cells up) that have
either a blank or some other non-number value.

The result should be 20 columns starting at, say, row 0, where each column
has up to 20 numbers, in original sequence, minus "blanks".

It could be done in-place if possible or somewhere else in the workbook.
Thanks in advance for the help
