MATLAB: For loop with non-linear input

for looprandom

Hi,

I have an array 'layer' that I want to randomise and use in a for loop, in the randomised order.

layer=0.05:0.0025:0.15;
rand_layer = randperm(length(layer));
layer=layer(rand_layer);

I can't use 'layer' as the input for the loop, so is there another way of have the input of the loop in the desired order?

Thanks,

Richard

for ii = 1:length(layer)
 do_stuff_with(layer(ii));
end

Never mind, I solved the problem this way:

X=0.05:0.0025:0.15;
randomiser = randperm(length(layer));
X=X(randomiser);

See if this does what you want:

F=96485; 
T=298; 
R=8.314;
% % % i=a*exp(-c*F*E/(R*T))+b*exp(-d*F*E/(R*T));                % Original Equation
% % % a = p(1),  b = p(2),  c = p(3),  d = p(4)                 % Define Parameters
fcn = @(p,E,i) p(1).*exp(-p(3)*F*E/(R*T)) + p(2).*exp(-p(4)*F*E/(R*T)) - i;
E = 42;                                                         % Use Correct Value

i = 24;                                                         % Use Correct Value
p0 = rand(4,1)*1E-6;
[Params,fval] = fsolve(@(p)fcn(p,E,i), p0)

If you have vectors of values for ‘E’ and ‘i’, use a nested loop to iterate through them:

E = [...];
i = [...];
for k1 = 1:numel(E)
    for k2 = 1:numel(i);
        Params{k1,k2} = fsolve(@(p)fcn(p,E(k1),i(k2)), p0);
    end
end
