The first function used can be found on the file exchange. To plot any points or contours you'll have to convert the CIE coordinates to MATLAB image coordinates (see the creation of nciex and nciey for example). I didn't plot the wavelengths around the arc, but you should be able to Wedges with the color of the common center point being white.
YTICK MATLAB 2008 SERIES
Play with the reference wavelengths, wl0, if you think you might be ableīasically, instead of a single polygon, we now have a series of small Isn't identical to the plot from wikipedia, but it's close.
YTICK MATLAB 2008 CODE
This code can be vectorized - I just didn't bother. % blue blue cyan green yellow orange red red % x_bar, etc are column vectors at wavelengths, wl. I finally had a chance to work on this some more. The hues are rather dark and it does not look like a CIE plot. The code you presented above has a bug : the reshape should be on x, y and I am using the following table for the tristimulus values and x, y and z : I will try to take it from here, but was wondering if you had any further Spectra of a bunch of LEDs onto a colored CIE plot like the one in the URL. I am trying to plot out CIE values (as isolated points) calculated from the Shape, marking out the locus of monochromatic emissions. The area inscribed by this shape is white/blank (needs to be coloredĪccording to the CIE coordinates). Thanks for the quick turn around (and happy new year !).Īll I get is a closed dark line defining the shape (that is what the patchĬommand does after the initial plot command plots an open curve in blue). Have to add contours / points to the plot to represent actual I have searched on file exchange, and though there are some hits thatĬome close (mainly relating to conversion of color spaces), there is Plot (the axis), while mixed colors define the interior. Monochromatic colours form the locus of the To the wavelength of light, which in turn corresponds (roughly) to theĬolour shown on the plot. The axis is in "bent" into that shape and each x axis value corresponds As I'm not sure exactly what you are trying to do I'll let you
YTICK MATLAB 2008 PATCH
The colors on that patch are about the correct hue, but most are tooĭark.
What is shown on the web page, you need to make a patch: Start by downloading the 1931 CIE color matching functions, x_bar, y_bar Have to add contours / points to the plot to represent actual experimental I have searched on file exchange, and though there are some hits that comeĬlose (mainly relating to conversion of color spaces), there is reallyĬan anyone suggest how this plot may be plotted ? After plotting, I would Monochromatic colours form the locus of the plot (theĪxis), while mixed colors define the interior. The wavelength of light, which in turn corresponds (roughly) to the colour
YTICK MATLAB 2008 MANUAL
This tool really fosters manual interaction and exploration of the user data. MATLAB is a leading program which has Data brushing a new feature that lets the user to manually select data on a plot. Variable Editor is a new addition that enhances the editing of Structures and Objects. Customizable toolbars will really help streamline the workflow of users, as they can arrange their toolbars based on how they use MATLAB. This customizable toolbar allows the user to change the order of toolbar elements, or remove things the users rarely use.
MATLAB 2008 allows the users to have a customizable desktop and editor with the presence of customizable toolbars. Furthermore, the new Development Environment features introduced in MATLAB 2008 allow MATLAB to customize the MATLAB Desktop and MATLAB Editor toolbars these inspect structures and objects with the Variable Editor and compare directories, other file types also publish functions and define configurations. MATLAB is very much sharp in doing tasks like linking plots to workspace variables and brushing data in plots for analysis and manipulation also editing tabular information in graphical user interfaces with new suitable control. The main focus of MATLAB is on creating multiple independent streams and using new algorithms with enhanced random-number generation features. MATLAB 2008 Matrix Laboratory is known as MATLAB.
