Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top.
Eb13 is Eb, G, Bb, Db, F and C — Eb9 with the thirteenth added on top.
It sounds big and open. Six notes will not fit under four fingers: the fifth goes first, then the ninth, and the third, flat seventh and thirteenth stay.

| Eb | G | Bb | Db | F | C |
|---|---|---|---|---|---|
| 1 | 3 | 5 | ♭7 | 9 | 13 |
Dominant — the full V chord.
Also written Ebdom13 or Eb dominant 13. The same chord either way; which spelling you meet depends on who wrote the chart.
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Eb13 has 2 of them, on strings 5-3-2-1 and strings 6-4-3-2, from the 6th fret up to the 11th — all in one inversion, so the bass note never moves. The one to learn first is the Eb shape at the 6th fret.
Start with x65688 — no barre and low, at the 5th fret. None of the shapes for Eb13 uses an open string, so every one of them is movable; the lowest sits at the 5th fret. 6 of the 8 need a barre. Together they cover the neck from the 5th fret to the 13th.

|---|---|---|---|---|
| x65688 | 5th fret | Eb, root position | C | all fretted |
| x65668 | 5th fret | Eb, root position | C | barred |
| 666688 | 6th fret | Bb, 2nd inversion | C | barred |

| 11-10-10-0-9-9 | 9th fret | Eb, root position | Db | 1 open string |
| 11-10-10-10-11-9 | 9th fret | Eb, root position | Db | barred |
| 11-11-11-12-13-13 | 11th fret | Eb, root position | F | barred |

Tensions. A shell of Eb13, root, third and seventh, leaves a string free, and the tones that belong over it are the #11 (A).
Eb13 is the V of Ab, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into Ab.
Voice by voice, Eb13 → Ab. 2 voices move by a semitone, and 2 notes are common to both chords.
| In Eb13 | Moves | In Ab |
|---|---|---|
| Eb, the root | stays where it is | Eb, the fifth |
| G, the major third | rises a semitone | Ab, the root |
| Bb, the fifth | falls a whole tone | Ab, the root |
| Db, the flat seventh | falls a semitone | C, the major third |
| F, the ninth | falls a whole tone | Eb, the fifth |
| C, the thirteenth | stays where it is | C, the major third |
