Comparing 2 arrays [message #55564]

Hi,

I would like to know if the data in two different 1 dimensional arrays
are the same or not. This should be for every index. For example, if
A=[0,1,2,3] and B=[0,1,3,2], then I would want the answer to be that A
and B are not equal even though they happen to have the same values in
different order. A problem with comparing each element is that the
numbers are floating point so I would prefer not to compare with
'EQ'. Has anyone any suggestions?

Alternatively, my arrays are actually from different structures. Is
there a way to compare structures? For example, data1.A vs data2.B in
the above example.

Thanks

Howie
