A Colormap Is An M-by-3 Matrix Of Real Numbers Between 0.0 And 1.0. Each Row Is An RGB Vector That Defines One Color. The Kth Row Of The Colormap Defines The Kth Color, Where Map(k,:)=[r(k)g(k)b(k)])specifies The Intensity Of Red, Green, And Blue. GRIDLINES, A MATLAB Code Which Draws Grid Lines On MATLAB Plots. MATLAB's Plotting Commands Include The "grid On" Option, Which Places A Certain Number Of Grid Lines On Your Plot. However, If You Don't Like The Choice Of Placement, Linestyle, Coloring, Or The Number Of Grid Lines, Changing These Features, While Possible, Requires An Extensive %Set Manuel's Color Preferences For Programming With Matlab And Fortran %% Setup The Color Pallet % Divide By 256 For Matlab Sol.base03 = [ 59 59 59] / 256; Sol.base02 = [ 7 54 66] / 256; You Can Choose The Color Of The Points, The Type Of Line Used, And The Shape Of Points Used By Adding A String Following The Arguments Of Plot. This Would Look Something Like Plot(x,y,'r-p'). In This Case, The 'r' Would Make The Line Red, The '-' Would Make A Straight Line Between The Points, And The 'p' Will Make The Points Appear As Stars. Each Row Of The Matrix Defines A Single Color By Specifying Three Values In The Range Of Zero To One. These Values Define The RGB Components (i.e., The Intensities Of The Red, Green, And Blue Video Components) Of Each Color. The Primary MATLAB Function Used For Color Mapping Is Colormap. Specify The Colors For A Mesh Plot By Including A Fourth Matrix Input, CO. The Mesh Plot Uses Z For Height And CO For Color. Specify The Colors Using Truecolor, Which Uses Triplets Of Numbers To Stand For All Possible Colors. When You Use Truecolor, If Z Is M -by- N, Then CO Is M -by- N -by-3.
