I want to draw trapezoidal fuzzy function in Matlab with codes below but error occurred using plot 3 and vector must be the same length

X1=linspace(0.143324275,0.148726949); X2=linspace(0.14826949,0.159464495); X3=linspace(0.159464495,0.164799513); X4=linspace(0.13788047,0.148726949); X5=linspace(0.159464495,0.170112121); Y1=(0.8*(x1-0.143324275))*(0.148726949-0.143324275).^-1; Y2=0.8; Y3=(0.8*(0.164799513-x3))*(0.164799513-0.159464495).^-1; Y4=(x4-0.13788047)*(0.148726949-0.13788047).^-1; Y5=1; Y6=(0.170112121-x5)*(0.170112121-0.159464495).^-1; Z1=1*(x1+1).^-1; Z2=1*(x2+1).^-1; Z3=1*(x3+1).^-1; Z4=1*(x4+1).^-1; Z5=1*(x5+1).^-1; Plot(x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4,x2,y5,z2,x5,y6,z5)

Please Note: You have defined X1, not x1 ..same for all...Matlab is case sensitive. Therefore X1 is different from x1

X1=linspace(0.143324275,0.148726949); 
X2=linspace(0.14826949,0.159464495); 
X3=linspace(0.159464495,0.164799513); 
X4=linspace(0.13788047,0.148726949); 
X5=linspace(0.159464495,0.170112121); 
Y1=(0.8*(X1-0.143324275))*(0.148726949-0.143324275).^-1; 
Y2=0.8; 
Y3=(0.8*(0.164799513-X3))*(0.164799513-0.159464495).^-1;
Y4=(X4-0.13788047)*(0.148726949-0.13788047).^-1; 
Y5=1; 
Y6=(0.170112121-X5)*(0.170112121-0.159464495).^-1; 
Z1=1*(X1+1).^-1; 
Z2=1*(X2+1).^-1; 
Z3=1*(X3+1).^-1; 
Z4=1*(X4+1).^-1; 
Z5=1*(X5+1).^-1; 
plot(X1,Y1,Z1,X2,Y2,Z2,X3,Y3,Z3,X4,Y4,Z4,X2,Y5,Z2,X5,Y6,Z5)
