SEGOVERLAP¶

The SEGOVERLAP function determines whether two segments overlap and returns a Boolean value.

Usage¶

SEGOVERLAP(x,y,a,b) : boolean

The following example shows a single NOR row with two segments x-y and a-b, which do not overlap. The test column will return 0.

NORROWS 1 | CALC x 10 | CALC y 20 | CALC a 25 | CALC b 35 | CALC test segoverlap(x,y,a,b)

In the next example, we show x-y overlapping a-b. The test column in this case will show 1.

NORROWS 1 | CALC x 10 | CALC y 20 | CALC a 15 | CALC b 25 | CALC test segoverlap(x,y,a,b)

To calculate the distance between two non-overlapping segments, use the SEGDIST function.
