Subroutine INTEG-PNTS

This subroutine generates the data about the Gauss point coordinates and the weight corresponding to various values of n (the number of Gauss points). We restrict the values of n to We use the following notation for the variables:

• Scalar variables:
  n : number of Gauss points (integer)
  
• Array variables
  psi (n) : Gauss point coordinates (real)
  w (n) : corresponding weights (real)
  
• INPUT variables : n

• OUTPUT variables : psi (n), w (n)

Now the subroutine can be written as follows.

Subroutine INTEG-PNTS (n, psi, w)
