how to save values in matlab after iteration

I have 2 for loops

    for c=1200:100:1600   
        for b=5:5:20

I want it to save the value in an array after finishing from 5 till 20 ex takes 1200 the iterates from 5 till 20 in specific equation before going back to c it saves the values in an array , then when taking 1300 also saves the values from 5 till 20 in a seperate array

cvals = 1200:100:1600;
bvals = 5:5:20;

for cidx = 1 : length(cvals)
  c = cvals(cidx);
  for bidx = 1 : length(bvals)
    b = bvals(bidx);
    .... compute something
    result{cidx}(bidx) = .... some scalar
  end
end

you didn't get my point , the ranges c and b are not in the equation itself, I have

 for c=1200:100:1600   
    for b=5:5:20 
computes several eqntions , b takes part in some eqntions

c is not used in the equations

last i have an equation

ex a=X+B

before it leaves I want the values of a to be saved in an array and then when it jumps to 1300 also the values of a in an another array

If u want I could give u a look at my code

You asked for storing in a separate array each time. Indexing a cell array by the c index will do that for you.

If c is not used in the equations then why bother to make it specifically 1200:100:1600 and why not just use 1 to 5 if you only care about the number of times it executes?

I could use 1 to 5 but I used 1200 till 1600 bcz I must show the tempratures i have taken in my code ,

Thanks man alooot , the code worked

But last questions , is their a way i could understand ur code and how it worked cz I have to make presentation to present

[Walter Roberson]

If you are not using the value of c then you have not used those temperatures in your code.

I recommend that you switch to 2-dimensional arrays:

cvals = 1200:100:1600;
bvals = 5:5:20;

for cidx = 1 : length(cvals)
  c = cvals(cidx);
  for bidx = 1 : length(bvals)
    b = bvals(bidx);
    .... compute something
    result(cidx,bidx) = .... some scalar
  end
end

Then you will have one row for each c value, which can be accessed as (for example)

result(3,:)

And printed out...

fprintf('for c = %f, b = %f %f %f %f\n', [cvals(:), result].')
