For loop with decimal number matrix

Hi,

Any help with this for loop. I write a for loop and i tell it to increment by a small value, let's say 0.01. This loop is simple example of my issue. In my code I need to create big zeros soultion matrix to save my results into it.

if my loop increment is decimal number, how should I write the soultion matrix?

Thanks

NTUmax=10;

tt=100;

Soulution=zeros(tt,NTUmax);

for i=1:NTUmax %% Incrementing value should be e.g equal 0.1

NTU=(i);

dtempdt=NTU*2;

Soulution(:,i)=dtempdt;

end

Why do you need a loop? , the answer is simpler than a loop.

Hi madhan ravi,

This is just an example. I have a complicated numerical code and it's not as simple as this example.

Thank you very much for your attention

I am not certain what you want to do.

If you want to use ‘i’ as a subscript, it must consist only of integers greater than 0.

This example creates ‘iv’ (your ‘i’ vector in 0.1 increments, the centre value in the ‘iv’ definition), then loops through it, defining ‘NTU’ in each iteration as an element of ‘iv’:

NTUmax=10;
tt=100;
Soulution=zeros(tt,NTUmax);
iv = 1:0.1:NTUmax; %% Incrementing value should be e.g equal 0.1
for i = 1:numel(iv)
    
    NTU =  iv(i);
    dtempdt=NTU*2;
    Soulution(:,i)=dtempdt;
    
end

Experiment to get the result you want.
