coneplot

Display 3-D vector directions with cone-style arrows.

📝Syntax

coneplot(X, Y, Z, U, V, W)
coneplot(X, Y, Z, U, V, W, cx, cy, cz)
coneplot(parent, ...)
h = coneplot(...)

📄Description

coneplot displays sampled 3-D vector directions using a patch object.

💡Examples

Display vectors on a 3-D grid.

% 3-D grid
[x, y, z] = meshgrid(-2:0.5:2, -2:0.5:2, -2:0.5:2);

% Synthetic vector field (rotation + divergence)
u = -y;
v = x;
w = z * 0.2;

% Cone positions
[cx, cy, cz] = meshgrid(-1.5:1:1.5, -1.5:1:1.5, -1.5:1:1.5);

figure
hcone = coneplot(x, y, z, u, v, w, cx, cy, cz, 0.4);
hcone.FaceColor = 'blue';
hcone.EdgeColor = 'none';
