我正在尝试在MATLAB中生成一个颜色图,给出三种颜色,一种是高极限,零极低.我的思维过程是从高端到中间循环并将每一步存储到3xN(第一列是R,第二列是G,第三列是B)矩阵.所以我正在使用：

%fade from high to zero

oldRed=high(1);

oldGreen=high(2);

oldBlue=high(3);

newRed=mid(1);

newGreen=mid(2);

newBlue=mid(3);

currentRed=oldRed; currentGreen=oldGreen; currentBlue=oldBlue;

for x=1:steps

currentRed=oldRed+((x*(newRed-oldRed))/(steps-1));

currentGreen=oldGreen+((x*(newRed-oldRed))/(steps-1));

currentBlue=oldBlue+((x*(newRed-oldRed))/(steps-1));

cmap=[cmap;[currentRed currentGreen currentBlue]];

end

然后我会做同样的事情从零值到低端.但是我的代码并没有给我任何有用的矩阵.有人能帮我解决这个问题吗？
