title: Using OpenGL shaders for math calculation (C++)
body: <p>I have a matrix (for example 100x100 dimantion):
  I need to do calculation with each element (<code>matrix[i,j]*tt/8+5</code> for example)</p>
  
  <p>I have huge matrix and I want to implement the algorithm using OpenGL shaders. 
  I want to use shader like:</p>
  
  <pre><code>uniform float val;
  uniform float tt;
  
  void main()
  {
      gl_Position.x = val*tt/8+5
  }
  </code></pre>
  
  <p>How I can implement the program? How I can get matrix after calculation(I do not want to show any windows\pictures?</p>
