Algorithm for Gauss Elimination Method

  • Start
  • Declare the variables and read the order of the matrix n.
  • Take the coefficients of the linear equations as:
    Do for k=1 to n
    Do for j=1 to n+1
    Read a[k][j]
    End for j
    End for k
  • Do for k=1 to n-1
    Do for i=k+1 to nDo for j=k+1 to n+1
    End for j
    End for i
    End for k
  • Compute x[n]=a[n][n+1]/a[n][n]
  • Do for k=n-1 to 1
    Do for j=k+1 to nsum=sum+a[k][j]*x[j]
    End for j
    End for k
  • Display the result x[k]
  • Stop
