However, I don't understand why - I thought I had
defined a one dimensional VERTICAL array.

The point is it must define a 2 dimensional array if multiple rows are
involved, 1st-rows, 2nd-columns even if there is only one column.

Thank you. That worked. However, I don't understand why - I thought I
had
defined a one dimensional VERTICAL array. It looked just like alot of
other
code I've seen. Even when I looked at the array in the locals window and
watch window, they showed all the values in a one dimensional array.

So it must have been something wrong with the assignation to the range.
Again, it looked like every other assignation I've seen for a one
dimensional
array. But if it works, I'm not complaining. I did have Options Base 1,
so
maybe that somehow affected it.

Really appreciate the quick help.

You have defined a 1D horizontal array. If you were to do

[a1:c1].value = arEMA

the ROW should be populated with the first three values of your array

Try it like this

Redim arEMA(1 to rows),1 to cols)

looks like you only have one column but include the second dimension
when
populating, eg
arEMA(1,1) = first value

I have created an array that stores prices. When my code writes the
values
of the array (single dimension, about 1500 elements), it writes the
value
of
the first element to every cell of the worksheet range. Relevant code
is
as
follows:

Dim Px As Single, EMA_0 As Single, EMA_1 As Single
Dim arEMA() As Single

nData = UBound(arPxData())
ReDim arEMA(nData)

arEMA(1) = arPxData(1)
For i = 2 To nData
arEMA(i) = (2 / (1 + nPeriods) * (arPxData(i) - arPxData(i -
1)))
+
arPxData(i - 1)
Next

With Range("OutEMA0Head")
Range(.Offset(1, 0), .Offset(nData, 0)).Clear
Range(.Offset(1, 0), .Offset(nData, 0)) = arEMA
End With

The Watch window shows that each element of the arEMA is filled with
different values. The .Clear line works perfectly. So does = arEMA
line,
except all 1500 cells are filled with the same value - the first
element
of
arEMA.

I don't want to have to loop through every cell, but it makes no sense
to
me
why this is happening.

Any suggestions would be appreciated.
