The following script (using your function) raised no exception so it
worked! Elegant Alex, thanx.
res = equalize_arrays(msgtmp,ppstmp,255) # class
(ppstmp,msgtmp) = res.equalize() # class method
for i in range(int(main.xsize)):
for j in range(int(main.ysize)
Hi Alex,
I will code this in a little while and get back to you. Terrific! I saw
this function but I skipped over it without realizing what it could do.
The Numeric doc is not very good and I am just getting into Python so
your book sounds great especially since it covers Numeric. I will look

Alex,
I am using Numeric and have created 3 arrays: zero((1215,1215),Float)
Two arrays are compared and one is used to hold the mean difference
between the two compared arrays. Then I compare 290 or 340 pairs of
arrays. I know that memory is a problem and that is why I don't open
all of these arra

Hi Gary,
I am really trying to cut the time down as I have 600+ arrays with
dimensions (1215,1215) to compare and I do a lot more things with the
arrays. If I understand you correctly, there is no way around a for
loop?

Hi,
I have two arrays that are of the same dimension but having 3 different
values: 255, 1 or 2.
I would like to set all the positions in both arrays having 255 to be
equal, i.e., where one array has 255, I set the same elements in the
other array to 255 and visa versa. Does anyone know how to do
