contour3

Contour 3D plot of matrix

Syntax

• contour3(Z)
• contour3(X, Y, Z)
• contour3(..., levels)
• contour3(..., LineSpec)
• contour3(ax, ...)
• M = contour3(...)
• [M, h] = contour3(...)

Input argument

• X - x-coordinates: vector or matrix.
• Y - y-coordinates: vector or matrix.
• Z - z-coordinates: vector or matrix.
• levels - Contour levels: scalar or vector.
• LineSpec - Line style and color
• ax - a scalar graphics object value: parent container, specified as a axes.

Output argument

• M - Contour matrix.
• h - a graphics object: contour type.

Description

contour3(Z) generates a 3-D contour plot illustrating the isolines of the matrix Z, where Z represents heights on the x-y plane.

The x and y coordinates in the plane correspond to the column and row indices of Z, respectively.

To specify the x and y coordinates for Z values, use contour3(X,Y,Z).

Example

f = figure();
[X,Y,Z] = sphere(50);
[M, C ]= contour3(X,Y,Z);
C.LineWidth = 3;
