how to obtain minimal surface of given coordinates?

patch = ([0,50,50,0],[0,0,50,50],[50,10,50,10])

[Seemab Khan]

minimal surface mean Optimal surface, whose surface is in equilibrium at each point.

Minimal in what sense?

 fill3( [0,50,50,0], [0,0,50,50], [50,10,50,10], 'y' ) ;
 grid on ;

[Seemab Khan]

Thanks a lot. minimal surface mean optimal surface, surface whose each point is in equilibrium.

Perhaps,

x = [0,50,50,0]; y = [0,0,50,50]; z = [50,10,50,10];
k = boundary(x(:), y(:), z(:));
plot3(x(k), y(k), z(k))
