Hello,

simple question.

Is it available to set val from 'accumarray(x,val)' which is non-consecutive?

For example,

x = size of (1500, 1 ) double , // interestrates actually,

y = size of (1500, 1 ) timestamp,

I'd like to compress y with yyyyMMWW, and x with average of matched column.

but it seems 'val' is not possbile to use with non-consecutive.

Also illustrate your need with an example.

You should have a look at findgroups() and possibly groupstats()
