matlab绘制梯形并标注参数

本文的目的: 绘制梯形并标注参数 参数为：斜率，上边沿的宽度以及各个转折点的标注 可以自行调参 Amp = 2; Fre = 2; Ste = 56; Breite = (1/(4*Fre))*((Ste/4/Fre-1)/(Ste/4/Fre))*2; x1 = (0+Ste/4/Fre)/Ste; x2 = (1+Ste/(4*Fre))/Ste; x3 = x2 + Breite; x4 = (0+(3*Ste)/(4*Fre))/Ste; figure(1) x = 0:0.00001:x4; y = trapmf(x,[x1 x2 x3 x4]); plot(x,y,'k',[x2 x2],[0 1.1],'--k',[0 x4],[0 0],'--k'); text(x2+Breite/3,0.95,['\uparrow ' 'Breite=' (num2str(Breite,2))]); text(x2+Breite/40,0.5,['\leftarrowSteigung=' (num2str(Ste,2))]); xlabel(['P = [',(num2str(x1,3)),', ',(num2str(x2,3)),', ',(num2str(x3,3)),', ',(num2str(x4,3)),']']) xlim([0 x4]) ylim([-0.05 1.05])
