| Parameter | Description |
|---|---|
| X | x-coordinates: vector or matrix. |
| Y | y-coordinates: vector or matrix. |
| C | Color array: m-by-n-by-3 array of RGB triplets. |
| parent | a scalar graphics object value: parent container, specified as a axes. |
| propertyName | a scalar string or row vector character. |
| propertyValue | a value. |
| Parameter | Description |
|---|---|
| go | a graphics object: image type. |
imagessc displays C data as an image. This image is colormapped using the colormap for the current figure.
Properties:
| Property | Description |
|---|---|
| AlphaData | Transparency data: scalar, array the same size as CData, or 1 (default). |
| AlphaDataMapping | Alpha data mapping method. |
| CData | Image color data: vector or matrix, 3-D array of RGB triplets. |
| CDataMapping | Color data mapping method: 'direct' or 'scaled' (default). |
| Children | []. |
| Parent | Parent: axes object. |
| Tag | Object identifier: string scalar, character vector, '' (default). |
| Type | Type of graphics object: 'surface'. |
| UserData | User data: array or [] (default). |
| Visible | State of visibility: 'off' or 'on' (default). |
