MATLAB: I am given set of five linear inequalities how to plot the graph showing the common area

2d plotconvex polygon

How can I draw 2D plot for these set of linear inequalities with ki representing x-axis and kd representing y-axis.The common area that is a convex polygon formed by these inequalities must be seen in the plot.The polygon should be in a way represented by picture below.

You can use lcon2vert,

to obtain the vertices V of the region. Then use plot(polyshape(V)).
A=[1,0;
   1,-0.2699;
   1,-0.3666;
   -1,+3.5358
   1,-13.5777];
b=[0,-4.6836,-10.0797,-3.912,140.2055].';
V=lcon2vert(A,b);
plot(polyshape(V))
