Plot projection of feasible region of linear programming in Matlab : Consider a linear programming in Matlab
`A x >= b`, `Aeq x = beq`, and `lb<=x<=ub`. I want to plot the feasibility region only for the first **three** (or, **two**) elements of the vector `x`. 

I found some codes that can plot the feasibility region (for example, [here][1]) provided that `x` is a `2x1` or `3x1` vector. 

Instead, in my case `x` is a `10x1` vector. However, I want to plot the feasibility region only for the first three (or, two) elements of `x`. I think this is basically the projection of the feasibility region along the first three (or, two) dimensions. 

Is there any code allowing to do that in Matlab? If not, could you advise on how to proceed?
