I have this function

function [I]= fick_diffusion(D, Cin,Cout,dist)

I = -D*((Cin-Cout)/dist)

end

I have all this parameters:

D= 2.1*10^-5

A = 30*40

Nin=20

Nout=0

dist = 40

while Nin>=10

[I] = fick_diffusion(D,Nin/A,Nout/A,dist)

Num_moving_part = -round(Nin*I*10^7)+2

Num_moving_location = randperm(Nin,Num_moving_part)

I need to find random location for the Num_moving_part when Nin and Nout are equal and there are only 20N together

and I need to subplot every move of the N and in a differnt color until in both side there are 10 N

When you go to plot a marker on your plots, choose a random color:

randomColor = rand(1, 3);
hold on;
plot(x, y, '.', 'Color', randomColor, 'MarkerSize', 30);

where x and y are scalars for just one point. This will plot all spots/markers in a different random color.
