You can use those numbers and divide the vector by 255 to use within matlab.

See this list for other built in colormaps.
Scatter 3d plot with varying colors.
What you re doing right now is passing in the colormap values which is unnecessary because the colormap is a property of the figure not the scatter plot.
Scatter3 or scatter takes in an argument c that allows you to color based on this input.
You can also use a specified line style marker and color for drawing 3d plots.
I want to plot these coordinates in a 3d graph using scatter3 or any other function where i need to plot each coordinate in a different color.
By default the points are colored according to their distance from the xy plane.
In matlab the plot3 function is used to draw the 3d plot graph.
For your case this is likely z.

2d scatter plot with z value in color.
Using rgb triplets to change colors one can specify colors using a vector that gives the rgb triple where in matlab each of the three values are numbers from 0 to 1.
Usually rgb colors have values from 0 to 255.
Figure scatter3 x y z s c view 40 35 corresponding entries in x y z and c determine the location and color of each marker.
The data points are sorted by color and plot3 is called once for each group of points that map to the same color.
I want to plot x1 y1 z1 in red x2 y2 z2 in yellow x3 y3 z3 in blue.
The general syntax to display the 3d plot is plot3 x y z plot3 x y z name plot3 x y z linespec.
This example uses jet and inputs the number of values in the first input to scatter3 x.
