Solution := backsub(S) 

should automatically be ploted where x=i*h and h=1/32 where i varies from 0 to m. 
 Secondly please let me know how to plot error graph where

error= exact solution - approximate solution

n both graph of exact solution and approximate solution is given in worksheet attached here checking.mw
Please Wait...
