# How can I change the MPS format in Linear Programming samples of Mathematica?

I am trying to play with some linear programming examples of Mathematica as ExampleData[{"LinearProgramming", "blend"}, "Equations"]. It gives me the MPS format of the samples. How can I change them?

You've seen this? –  Guess who it is. May 6 '13 at 11:13

One thing you can do is to import in the ConstraintMatrix form.
 Import["ExampleData/afiro.mps", "ConstraintMatrix"]

This gives a SparseArray object, which can be turned back into a regular matrix format using Normal. Some other possible manipulations of the MPS data are discussed here.
Could you please show me how I can use the Normal and after changing it how having new SparseArray again? –  Alex May 6 '13 at 17:52
After applying Normal it is a matrix of values and you can do anything with it you desire. If you name it (say m) then you can get back to sparse form by SparseArray[m]. –  bill s May 6 '13 at 17:57
