quiver

2-D vector field plot.

📝Syntax

quiver(U, V)
quiver(X, Y, U, V)
quiver(..., scale)
quiver(..., LineSpec)
quiver(..., propertyName, propertyValue)
quiver(parent, ...)
h = quiver(...)

📥Input Arguments

Parameter	Description
X, Y	Arrow base coordinates, specified as scalars, vectors, or matrices.
U, V	Vector components, specified as numeric arrays of the same size.
scale	Automatic scale factor. Use 0 to disable automatic scaling.
LineSpec	Line style, marker, and color specification.
parent	Axes or hggroup parent.
propertyName	Scalar string or character vector property name.
propertyValue	Property value.

📤Output Arguments

Parameter	Description
h	Quiver graphics object.

📄Description

quiver(U,V) plots arrows with vector components U and V on a regular grid.

quiver(X,Y,U,V) plots arrows at the coordinates specified by X and Y.

See quiver properties for the complete property list.

💡Examples

Plot a vector field on a regular grid.

[X, Y] = meshgrid(-2:0.5:2, -2:0.5:2);
U = -Y;
V = X;
h = quiver(X, Y, U, V);
axis equal

Style the arrows and disable automatic scaling.

x = 1:5;
y = [1 2 1 2 1];
u = [1 0 -1 0 1];
v = [0 1 0 -1 0];
h = quiver(x, y, u, v, 0, 'r--o', 'LineWidth', 1.5);
h.ShowArrowHead = 'on';
