我做错了什么？ [MATLAB - 函数填充]

Question

我怎样才能填写下面的区域？

我尝试创建两个多边形并使用填充函数，但我的方法均无效。这是我获得的最好成绩：

batha = [7.1333, 7.2417, 8.9061, 11.3646, 12.4889, 13.4572, 14.2250, 14.9386, 15.6905, 16.3310, 16.9292, 17.5558, 18.1131, 18.6633, 19.1629, 19.6635, 20.1515, 20.5933  21.0977, 21.5496, 21.9330, 22.2395, 22.5265, 22.7585, 23.1206, 23.4995, 23.9305, 24.2578, 24.6371, 25.1523, 25.4367, 25.6555, 25.9033, 26.1234, 26.2947, 26.4327, 26.5938, 26.6785, 26.7185, 26.7620, 26.8082, 26.7954, 26.7736, 26.7620, 26.7115, 26.5621, 26.3871, 26.1397, 25.9179, 25.6900, 25.4573, 25.1153, 24.7805, 24.4380, 24.0568, 23.7017, 23.3502, 22.9135, 22.5052, 22.0068, 21.4806, 21.0029, 20.5206, 20.0435, 19.5195, 18.9530, 18.4100, 17.9349, 17.4666, 17.0207, 16.5991, 16.1766, 15.8215, 15.6079, 15.4509, 15.2146, 14.9472, 14.7120, 14.3792, 14.0351, 13.7436, 13.4690, 13.1548, 12.9656, 12.8458, 12.6870, 12.5101, 12.2376, 11.8062, 11.3752, 10.9464, 10.4963, 10.0391, 9.5816, 9.1367, 8.7270, 8.2709, 7.7497, 7.0903, 6.1263];
bdii = [0, 0.0303, 0.0606, 0.0909, 0.1212, 0.1515, 0.1818, 0.2121, 0.2424, 0.2727, 0.3030, 0.3333, 0.3636, 0.3939, 0.4242, 0.4545, 0.4848, 0.5152, 0.5455, 0.5758, 0.6061, 0.6364, 0.6667, 0.6970, 0.7273, 0.7576, 0.7879, 0.8182, 0.8485, 0.8788, 0.9091, 0.9394, 0.9697, 1.0000, 1.0303, 1.0606, 1.0909, 1.1212, 1.1515, 1.1818, 1.2121, 1.2424, 1.2727, 1.3030, 1.3333, 1.3636, 1.3939, 1.4242, 1.4545, 1.4848, 1.5152, 1.5455, 1.5758, 1.6061, 1.6364, 1.6667, 1.6970, 1.7273, 1.7576, 1.7879, 1.8182, 1.8485, 1.8788, 1.9091, 1.9394, 1.9697, 2.0000, 2.0303, 2.0606, 2.0909, 2.1212, 2.1515, 2.1818, 2.2121, 2.2424, 2.2727, 2.3030, 2.3333, 2.3636, 2.3939, 2.4242, 2.4545, 2.4848, 2.5152, 2.5455, 2.5758, 2.6061, 2.6364, 2.6667, 2.6970, 2.7273, 2.7576, 2.7879, 2.8182, 2.8485, 2.8788, 2.9091, 2.9394, 2.9697, 3.0000];

%Adjusting the bathymetry

batha=-1.*batha;


plot(bdii,batha(1,:),'k'); hold on;

x0 = min(bdii);
y0 = max(batha);
x1 = max(bdii);
y1 = min(batha);

fill([x0, bdii],[y0, batha],'g');
fill([x1, bdii],[y1, batha],'y');

我尝试了

fill

和

area

功能。
