Matlab blue colormap

RGB colormap, specified as a c-by-3 numeric matrix with values in the range [0, 1]. Each row of map is a three-element RGB triplet that specifies the red, green, and blue components of a single color of the colormap. If you have Parallel Computing Toolbox™ installed, map can also be a gpuArray.
colormap map sets the colormap for the current figure to one of the predefined colormaps. If you set the colormap for the figure, then axes and charts in the figure use the same colormap. The new colormap is the same length (number of colors) as the current colormap.

Jan 10, 2019 · The "ice" colormap is designed to mimic the way sea ice looks in the ocean. Zero concentration of sea ice looks like a dark blackish blue, whereas 100% sea ice cover is nearly pure white. If you prefer to flip the order of any colormap, the flipud command is one way to do it. A simpler way is to use the - sign when you call the colormap. For ...

- MATLAB ® draws the objects by mapping data values to colors in the colormap. Colormaps can be any length, but must be three columns wide. Each row in the matrix defines one color using an RGB triplet. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color.

This was done above when showing the previous default colormap. Here are some more. Warning! Once you change the colormap, it will keep that colormap for all subsequent 3D plots within the same figure or MATLAB session until you use close, or open a new figure window. imhist(img,n) displays a histogram with n bins for the intensity image above a grayscale colorbar of length n. If we omit the argument, imhist() uses a default value of n = 256 if I is a grayscale image, or n = 2 if I is a binary image.
