Dear all

I would like to store each output from a loop to a matrix M.

I have some dificulties due to indexing.

Could someone plese give me a help on this problem?

Thank you very much

Dear Matt

Please find the code on a copy/pastable form. I have created a simplifed table, to run the code here. The values are diferent but the issur is the same.

Thank you for your help.

n1=([2 2 3 2 1 4])'; 
dbL1=([10 12 10 10 10 10])';
n2=([0 0 0 1 2 0])' ;
dbL2=([0 0 0 12 12 0])' ;
Asst=([0.00015708 0.00022619 0.0023562 0.00027018 0.00030473 0.00031416])';
Asneg =([0.00033466 0.0002799 0.0005958 0.00051939 0.00028386 0.0002758])';
As=table(n1, dbL1,n2,dbL2,Asst)
As = 6×5 table
    n1    dbL1    n2    dbL2       Asst   
    __    ____    __    ____    __________

    2      10     0       0     0.00015708
    2      12     0       0     0.00022619
    3      10     0       0      0.0023562
    2      10     1      12     0.00027018
    1      10     2      12     0.00030473
    4      10     0       0     0.00031416
for j=1:3
    
    As_prov=As.Asst>Asneg(j);
    
    i=find(As_prov,1,'first')
    
    n1=As.n1(i)
    dbL1=As.dbL1(i)
    n2=As.n2(i)
    dbL2=As.dbL2(i)
end
i = 3
n1 = 3
dbL1 = 10
n2 = 0
dbL2 = 0
i = 3
n1 = 3
dbL1 = 10
n2 = 0
dbL2 = 0
i = 3
n1 = 3
dbL1 = 10
n2 = 0
dbL2 = 0
