hy, i have to find the feaseble place for any given system of inequalities.

One way is to use lcon2vert downloadable from here,

https://www.mathworks.com/matlabcentral/fileexchange/30892-analyze-n-dimensional-polyhedra-in-terms-of-vertices-or-in-equalities

A=[-3 -2;1 -1; -1/5 1]; b=[-6;1;1];
V=lcon2vert(A,b);
plot(polyshape(V))

HY, thank you for the response. I have to use sym for the values and it should work for any system of inequalties(es: {x^2-4<0, x+y-1<0). I am new to matlab and from simple examples to this is a bit too much...

I don’t think it’s possible. Finding the feasible region of general inequalities is nontrivial...
