title: How do I install C packages on windows
body: <p>I have to use LU decompostion to fit a simple model to some data (simulated) in C. An example of what I need to do is <a href="https://stackoverflow.com/questions/3519959/computing-the-inverse-of-a-matrix-using-lapack-in-c">here</a>:</p>
  
  <p>However, I'm stuck with a more basic problem: how do I install packages in C and call them in my code?</p>
  
  <p>I'm new in C and I'm used to R. But I have this assingment to do some tests about Matrix inversion, LU decomposision and the professor suggested using Lapack to easy things (thus, I don't need to code myself the LU decomposition etc.). But I don't know how to install the package and call it in my code, in order to use the functions of LAPACK.</p>
  
  <p>I have a windows 7 64 bits and I'm using compiler Code Blocks 8.02</p>
  
  <p>Thanks for any help.</p>
