Take the grade membership function as an example:

score.m

cj_x1=[0 0.1];
cj_y1=[1 0];
cj_x2=[0 0.1 0.33 0.43];
cj_y2=[0 1 1 0];
cj_x3=[0.33 0.43 0.66 0.76];
cj_y3=[0 1 1 0];
plot(cj_x1,cj_y1,'b-',cj_x2,cj_y2,'r-',cj_x3,cj_y3,'m-');
title( ' Grade membership function ' );
legend( ' Failed ' , ' Good ' , ' Excellent ' )
xlabel( ' normalized score ' ), ylabel( ' membership ' );
axis([0 0.8 0 1.3]);

result:
