Description |
|---|---|
|
out = image(x,y,z); |
Creates a 2D image plot of the data in z. If x is of dimension N x 1 and y is of dimension M x 1, then z must be of dimension N x M. The figure number is returned. |
|
image(x,y,z, "x label", "y label", "title"); |
Creates a 2D image plot with axis labels and a title. The figure number is returned. |
|
image(x,y,z, "x label", "y label", "title", "options"); |
Creates a 2D image plot with axis labels and options, options can be

Example
This example generates a figure of the 2D function pic(x,y)=sin(x)+sin(y).
x=linspace(0,10,100); y=linspace(0,10,100); x2=sin(x); y2=sin(y); pic=meshgridx(x2,y2)+meshgridy(x2,y2); image(x,y,pic,"","","","logplot"); image(x,y,pic,"","","","logplot,red2blue");
The following figures show the output of the example code.
