To understand this lets first create a surface plot with some colormap: Each row of the matrix will be an RGB triplet color value that will specify one color of the colormap. This command returns the colormap for our current figure as a 3-column matrix utilizing RGB triplets. So, as per the table above for colormap codes, let’s use ‘parula’ as our colormap and let use 5 as the number of colors that we want to use out of ‘parula’ colormap. We can use this command if we want to set the colormap for our current figure to the colormap specified by the argument ‘map’. We can change our output back to the default value by simply using the command:

The axes and charts in the figure will use the same colormap as the predefined colormap selected by us.Įxample: We will create a surface plot and will set the colormap to ‘summer’ (which is a pre-defined colormap) While using this command, we cannot specify the length of colormap as per our choice. This command is used to set the color of the figure to some predefined colormap. Let us now understand these ones by one with the help of examples: MATLAB also supports some predefined colormaps.īelow is the table showing codes for these predefined colormaps:īelow is the list of SYNTAX used for colormap:Ĭmap = colormap Examples of Colormap in Matlab
MATLAB COLORMAP FULL
0 indicates no color & 1 indicates the full intensity of the color.īelow is the list of RGB triplets to get various colors: Color As mentioned above, these intensities are in the range. As you might be aware, the RGB triplet is a 3-element row vector with its elements specifying the intensities of red, green & blue color. Each row of the matrix defines one color by using an RGB triplet. A colormap is basically a matrix with values between 0 & 1.Ĭolormaps can have any length, but width-wise they must have 3 columns.
MATLAB COLORMAP PATCH
As the name suggests, the purpose of colormap is to define the colors of the graphics objects like image, surface and patch objects. The objective of this article is to have a thorough understanding of colormaps in MATLAB. MATLAB comprises a number of techniques and functions to perform the above-mentioned capabilities.
