COMPRESSI (and J,K,L,M,N)

Last modified: Mon, 04/16/2018 - 17:03

COMPRESSI(DAT) Returns data, compressed along the I axis: Missing points are moved to the end

Likewise COMPRESSJ, COMPRESSK, COMPRESSL, COMPRESSM, COMPRESSN compress data on the given axis, returning data on an abstract axis on that axis.

Arguments:

DAT

DAT: variable to compress in I

Result Axes:

X

ABSTRACT, same length as DAT x-axis
 

Y

Inherited from DAT
 

Z

Inherited from DAT
 

T

Inherited from DAT
 

E

Inherited from DAT
 

F

Inherited from DAT

Note:
It is generally advisable to include explicit limits when working with functions that replace axes. for example, consider the function compressi(v). The expression

list/i=6:10 compressi(v)

is not equivalent to

list compressi(v[i=6:10])

The former will list the 6th through 10th compressed indices from the entire i range of variable v. the latter will list all of the indices that result from compressing v[i=6:10].
