Appendix A

 

EXPNDI_BY_M_COUNTS(dat, counts, max_profile_len)

Expands arg1 on I into an XE grid. (To split observatiosn into E rows). For instance, the counts may be the ROWSIZE variable in a Discrete Geometries dataset which represents profiles.
 

Arguments:

DAT

Variable to expand. A 1-D list on the X axis
 

COUNTS

 The count of values in each profile or other feature type
on an E axis
 

MAXLEN

 The maximum count or rowsize for any feature:
I-size of the result

Result Axes:

X

Abstract: Length is the number of features, length of argument 2
 

Y

NORMAL
 

Z

NORMAL
 

T

NORMAL
 

E

Abstract: length given by argument 3
 

F

 NORMAL

 

Example:

yes? let var = {1,2,3,4,5,6,7,8,9}
yes? let counts = esequence({1,3,5})
yes? list EXPNDI_BY_M_COUNTS(var,counts[m=1:3],5)
 VARIABLE : EXPNDI_BY_M_COUNTS(VAR,COUNTS[M=1:3],5)
 SUBSET : 5 by 3 points (X (Obs)-E (Row))
 1 2 3 4 5 
 1 2 3 4 5
 1 / 1: 1.000 .... .... .... ....
 2 / 2: 2.000 3.000 4.000 .... ....
 3 / 3: 5.000 6.000 7.000 8.000 9.000
