[求助] potential step voltammetry

大家好，最近老师让做一道题，用matlab模拟电势阶跃。对于从来没有接触过matlab的小虫来说，实在不知道怎么入手。在此跪求大神帮我写个code。金币不是问题。

Potential Step Voltammetry
a) (20  points)  Using  MATLAB software (pdep  solver),  write  a  computer  code  that  can  be
used  to  simulate  a  potential  step  experiment  at  a  planar  electrode  to  any  arbitrary
potential. Assume the following:
1. The only reaction that occurs: O + e-  ←→ R
2. D iffusion coefficients are equal: Do = DR  = D = 1 x 10- 9m2/s
3. O is initially present at a concentration of 1 mole/m3 and R is initially absent
4. Eo’= 0  V/SHE,  A = 1 cm2, T = 298 K
b) (10 points) From the code above, make plots of the concentration profile as a function of
distance from the electrode surface and  current as a function of time for the conditions
below. Also, plot the analytical solutions (see section 5.5.1) on all graphs.
1. ko =  1.0 x 10- 5  m/s, α = 0.5, and E =  - 0. 01,  - 0. 05,  - 0.1  V/SHE
2. ko  = 1.0 x 10- 7 m/s, α = 0.5, and E =  - 0.01, - 0.05, - 0.1 V/SHE
3. ko  = 1.0 x 10- 9m/s, α = 0.5, and E =  - 0.01, - 0.05, - 0.1 V/SHE
c) (10 points) Discuss your results from part (b).
