HPGCC3 - symbolic matrix vs array

[multilingualtricker]

Hello!

Don't know if anyone has any suggestions on this issue?
Am getting better at making programs on HPGCC3 (many thanks to Gjermund for this)

HPGCC3 seems to only like arrays (type 3) rather than symbolic matrices (type 29)

Quite often I want it to operate on arrays that have the occasional NAN (not a number) in them which invariably turns the object into a type 29.

What I wanted to know is, is there some replacement for NAN that I could use which would maintain the type 3 status of the array, but would not get involved in the maths in HPGCC3? (e.g. when calculating the average of numbers in a column)

The other solution is to get rid of NANs in a wrapper and then feed into HPGCC3, but this throws up problems of it's own e.g. the columns of the matrix might not maintain equal length etc.

Many thanks!

p.s. just on the subject of HPGCC3, has anyone noticed that this program causes the TICKS to run backwards (i.e. the latter tick ends up being before the initial tick somehow??)
