Linear and Non linear solution of stiff problem

I have developed some formula in block form? and need Fortran code to use them in solving Linear problem by guessian ellimination and non linear problem by Modified Newton's method. ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details. Should a dispute arise and this project go into arbitration "as is", the contract's vagueness might cause it to be interpreted against you, even though you were acting in good-faith. So for your protection, if you are interested in this project, please work-out and document the requirements onsite. The blocked formula is a numerical formula that is continues and self starting to generate solution y(i)? at a constant step length within certain interval and should be able to give the values of the of the exact solution, absolute error between the exact and the numerical solution at all points in the interval, number of iteration, time taken for each iteration to converge, ? and order of the methods . All these should be shown in a? tabular form for the Non linear solution.? While for the linear solution the table should include each point x(i) of the interval , y(i) of the numerical solution Y(i) of the exact solution , absolute error between the exact and numerical solution, order of the methods .
