La fusion de deux chiffres dans Matlab

Je suis en train d'exécuter un script Matlab (ci-dessous) qui produit quatre séparée graphiques. Je veux combiner deux de ces graphiques, de sorte que le sont affichées simultanément. Les graphiques je souhaite combiner j'ai fait référence à la FIGURE 2 et la FIGURE 4 dans le script ci-dessous.

La seule entrée pour le script est un fichier txt avec 6 colonnes: les coordonnées x, y les coordonnées et 4 variables (Profondeur [m], Hsig [m] , Période de [s] , Dir [degrés])

Toute aide serait grandement appréciée.
