Hello !
In my program, I have two vectors V1 and V2 as follows:
V1 =[0 20 60 80 100]
V2 =[20 60 80 100]
i want to run my program for V2 and each element of V1, it means
i run my code 10 iterations for each element
V2=20 , V1= 0
V2=60 , V1=0
V2=80 , V1 =0
V2=100 , V1=0
after this
V2=20 , V1=20
V2=60 , V1=20
V2=80 , V1 =20
V2=100 , V1=20
until all the elements of V1 are completed, each time I get a result, I want to put it in the matrix to see the result of 10 iterations of each association between elements of V1 and V2.
thanks in advance

V1 =[0 20 60 80 100];
V2 =[20 60 80 100];
itermax = 10;
for i = 1:numel(V1)
v1 = V1(i);
for j = 1:numel(V2)
v2 = V2(j)
for iter = 1:itermax
% Calculate some quantity depending on v1 and v2 and save it as result(i,j)
end
end
end

@Torsten Hi! the code you provided doesn't work in my code case because i have many for loops and the final result does not directly related to V1 and V2 ,So I try to explain more about the method I want to use to make it easier.
i keep the vector V1.
for V2 i generated with same dimension of V1 starting from the first element as follow
V1 =[0 20 60 80 100];
V2 =[20 20 20 20 20];
i did 10 iterations , i wrote the result in form of cell (5 cell) in each cell 10 results of 10 iterations.
Now i want to change V2
V1 =[0 20 60 80 100];
V2 =[60 60 60 60 60];
here V1 and V2 are two examples so if the vector have less elements i can do it , but the problem in my real case V1 and V2 have 50 elements, so i need a loop to replace each time V2 and the result will be saved in cell like i did exactly with one value.
