Aqueous solutions containing approximately 3 percent(w/w) H2O2
are sold in drug stores as a disinfectant. Determination of the
actual concentration of H2O2 in a bottle of peroxide solution was
done by diluting 1.00 mL to 100 mL with water, acidifying with
dilute H2SO4 and titrating with a 0.01231 M KMnO4 solution. If
41.92 mL of the permangate solution was needed to reach the end
point of the titration, what is the actual molar concentration of
the H2O2 solution? Hint: Balance...

i wish to solve the equations v'=v^3/3-w+i, w'=g(v+a-bw) with
a=0.8, b=0.7, g=0.08, i=0.5 using ode45 in matlab. i solved in on
paper but i don't know how to type the codes in matlab.
i googled this but for one unfamiliar with the code, it is hard
to fathom what they are solving i also would like the code to show
the plots of both variables changing with time and the phase plots
of both variables.
