# bone

Bone colormap array

## Syntax

``c = bone``
``c = bone(m)``

## Description

example

````c = bone` returns the bone colormap as a three-column array with the same number of rows as the colormap for the current figure. If no figure exists, then the number of rows is equal to the default length of 64. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color scheme looks like this image. ```

example

````c = bone(m)` returns the colormap with `m` colors.```

## Examples

collapse all

Plot a surface and assign the bone colormap.

```surf(peaks); colormap('bone');```

Get the bone colormap array and reverse the order. Then apply the modified colormap to the surface.

```c = bone; c = flipud(c); colormap(c);```

Get a downsampled version of the bone colormap containing only twenty colors. Then display the contours of a paraboloid by applying the colormap and interpolated shading.

```c = bone(20); [X,Y] = meshgrid(-10:1:10); Z = X.^2 + Y.^2; surf(X,Y,Z); colormap(c); shading interp;```

## Input Arguments

collapse all

Number of entries, specified as a scalar integer value. The default value of `m` is equal to the length of the colormap for the current figure. If no figure exists, the default value is 64.

Data Types: `single` | `double`
