Do you include following m$-$files?

HW$4\_$yourEmailAccount.m$,$

fixedPoint$\_$yourEmailAccount.m$,$

Newton$\_$yourEmailAccount.m$,$

secant$\_$yourEmailAccount.m$,$

modifiedSecant$\_$yourEmailAccount.m$,$ and

nonlinerNewton$\_$yourEmailAccount.m

Are your dat file names following correct format like

HW$4\_$numbering.dat?

Do you erase "clear all" and "close all" statement?

Do you use ; at the end of each statement?

If 'erel' is not specified, use $0\mathrm{.}0001\%$ as a default value.

If 'maxit' is not specified, use $50$ as a default value.

Fixed Point Method, Newton$-$Raphson Method, &

Secant Method

Determine the highest real root of $f_5(x)=2x^3-11\mathrm{.}7x^2+17\mathrm{.}7x-$

$5$:

Graphically $($Just for checking out$)$

Use fixed point iteration method $($three iterations, $x_0=2\mathrm{.}9).$

save the root on HW$4\_1.$dat file

save the estimated error ${}_a$ on HW$4\_2.$dat file

show all steps of three iterations by hands. $($use an engineering

paper.$)$

Use Newton$-$Rapson method $($three iterations, $x_0=2\mathrm{.}9).$

save the root on HW$4\_3.$dat file

save the estimated error ${}_a$ on HW$4\_4.$dat file

show all steps of three iterations by hands. $($use an engineering

paper.$)$

Use Secant method $($three iterations, $x_{-1}=2\mathrm{.}9,x_0=4).$

save the root on HW$4\_5.$dat file

save the estimated error ${}_a$ on HW$4\_6.$dat file

show all steps of three iterations by hands. $($use an engineering

paper.$)$

Use Modified secant method $($three iterations, $x_0=2\mathrm{.}9,=0\mathrm{.}2).$

save the root on HW$4\_7.$dat file

save the estimated error ${}_a$ on HW$4\_8.$dat file..... matlab code please
