How can I store the output from each for loop as a unique variable?

How can I store the output for each loop as a seperate variable. Eg. for k=3 creates 3 variable, total_year1, total_year2 and total_year 3...total_yeark?

k= input('Enter the no. of years'); for x=1:k M1=input(strcat('Enter the number of runs in year',' ', num2str(x),'match 1')) M2=input(strcat('Enter the number of runs in year',' ', num2str(x),'match 2')) M3=input(strcat('Enter the number of runs in year',' ',num2str(x), 'match 3')) total_year1=(M1+M2+M3) end

That is exactly what you should not do. Magically creating or accessing variable names is how beginners write complex, slow, inefficient, buggy code. It is much better to use indexing: faster, neater, simpler, easier to debug, much more efficient.

The documentation has an entire page which explains why you should avoid doing exactly what you are asking about. It states: "A frequent use of the eval function is to create sets of variables such as A1, A2, ..., An, but this approach does not use the array processing power of MATLAB and is not recommended. The preferred method is to store related data in a single array." Storing your data in one array and using indexing is what you should be doing.

Store the data in one array as follows:

result(x)=M1+M2+M3;
