# Storage of variables being generated in a loop

3 views (last 30 days)
Hy guys!
My code uses random variables to generate times of up and down of components and feed a state map. and im using the sum of the times to calculate indexs.
I need to store theses indexes to make an average of them(10 is good enough)
Here's my code:
U=rand(n,1);
for i=1:n
%Primeiro Tup
T7=-1*log(U)/((lambdaT+lambdaP));
end
%0 = Up
%1= down transitorio
%2= down permanente
% Primeiro tempo, todos os componentes ON
Tclock7=zeros(1,n);
%Calcular o menor T para ver o componente que ira transitar de estagio
comp=find(T7==min(T7));
%Mudando estado do componente envolve sortear se caso esteja transitando
%de ON para OFF sera a falha permanente ou transitoria
if Tclock7(comp)==0
if rand>0.111
Tclock7(comp)=1;
mi=mit(comp);
else
Tclock7(comp)=2;
mi=mip(comp);
end
else
Tclock7(comp)=0
end
% Calculando Tdown do primeiro Componente off
T7(comp)=T7(comp)-1*log(U2)/((mi*trecho(comp))/horas);
% Encontrando próximo componente a transitar
comp=find(T7==min(T7));
if Tclock7(comp)==0
if rand>0.111
Tclock7(comp)=1;
mi=mit(comp);
contT7=1;
contP7=0
else
Tclock7(comp)=2;
mi=mip(comp);
contP7=1;
contT7=0;
end
else
Tclock7(comp)=0
end
Tclock7=Tclock7;
T7=T7;
% Calculando novo Tup ou Tdown
% Essa rotina tem que ser automatizada até que todos os componentes cheguem
% a 8760 para fazer a avaliação dos criterios de disponibilidade de 1 ano
% Iteração para todos os componentes(17) chegarem a 1 ano de planejamento
%Variaveis de contagem
iter7=1;
contON7=0;
w=10;
%Loop para analisar todos os componentes
while length(S7) < 10
for all=1:n
%Loop para chegar até analise de 1 ano
while T7(all)<horas
iter7=iter7+1;
%Encontrar qual componente transita
comp=find(T7==min(T7));
%Caso o componente esteja DOWN
if Tclock7(comp)==1 | Tclock7(comp)==2
%Transicoes para ON
contON6=contON6+1;
%Calculo do TUP
T7(comp)=T7(comp) -1*log(rand)/((lambdaT+lambdaP));
%Faz a transiçao no mapa de estados
Tclock7(comp)=0;
% Caso o componente esteja UP
else Tclock7(comp)=0;
%Sorteio para ver se a falha sera transitoria ou permanente
if rand>0.111
% Puxo o mi transitorio
mi=mit(comp);
T7(comp)=T7(comp)-tmorto;
%Faz a transicao no mapa de estados
Tclock7(comp)=1;
% Contador de numero de falhas transitorias por ano
contT7=contT7+1;
%Puxo o mi permanente
else mi=mip(comp)
%Faz a transicao
Tclock7(comp)=2;
%Variavel aleatoria para calcular TDOWN
U3=rand;
%Contador de numero de falhas permanentes por ano
contP7=contP7+1;
end
%Calculo do TDOWN
T7(comp)=T7(comp) -1*log(U3)/((mi)*trecho(comp)/horas);
TDT7=(-1*log(U3)/((mi)*trecho(comp)/horas));
TDT7=TDT7+(-1*log(U3))/((mi)*trecho(comp)/horas);
% Indice de Frequencia
% SAIFI
consumidores=sum(consumidores);
saifi7=contP7/consumidores;
%SAIDI - indice de duraçao das interrupcoes sustentadas
saidi7=TDT7/consumidores;
%ASAI
for m=1:10
asai7=(horas*n-TDT7)/(horas*n);
S7=[asai7(m)]

Doesnt work

Since you refuse to provide working code and don't provide any details about what you mean with "Doesnt work" it is very hard to help you. I can't run your code, so I can't diagnose your problem for you. The choice is yours:
1. provide a fully working example (attach data in a mat file if you need to)
2. provide much more details about what you mean by "Doesnt work"
3. only provide incomplete descriptions of failure and/or code that cannot be run independently
If you go for option 3 I will not be able to help you. Please let me know your choice, because if it option 3 I know I am wasting my time.
Thank you a lot for your time Rik! I got it by other way. The way you were sugesting would'nt work cuz my while loop would stop every time it reached the sample(horas) I seted.
So I just raised my time of iteration in my main while loop, and divided my indexes vector to the new sample I wanted to set(ask for input), and also created a for only to build my indexes..

The general solution to a problem like this is to put some code around it. The most general solution is to use cell arrays, but if you already know the dimension and type it is a better idea to use an array.
%example of working code:
a=10;b=100;c=30;
some_output=sum(rand(a,b)*c,'all');
some_output2=a*b/c;
array_out_1=cell(10,1);
array_out_2=cell(10,1);
for n=1:numel(array_out)
%first run the working code
a=10;b=100;c=30;
some_output=sum(rand(a,b)*c,'all');
some_output2=a*b/c;
%then store your variables of interest to the cell arrays
array_out_1{n}=some_output;
array_out_2{n}=some_output2;
end
