MATLAB: Drawing a trapezium in matlab

Question

Is there a quick way, apart from using vertices, to draw an isosceles trapezium given the height and the length of both parallel sides? Thank you.

Answer 1

h = 1 ;  % height 
a = 2 ;  % top side
b = 4 ;   % base 
%%Frame vertices
A = [0 0] ;
B = [b 0] ;
C = [0.5*(b-a)+a h] ;
D = [0.5*(b-a) h] ;  
coor = [A ; B; C; D] ;  
patch(coor(:,1), coor(:,2),'r')
