Trying to Save all my inputted data from my for loop. I need to save the the Values of A,B and C into one matrix.

Components = input('Enter Number of Liquid Components:' )

x = Components;

for r = 1:x

       A = input('Enter A:');
       B = input('Enter B:');
       C = input('Enter C:');

end

Sayyid - if you are expecting the user to enter numeric data, then you could just use an array to store this information. Try something like the following

 numComponents = input('Enter Number of Liquid Components:' )
 componentData = zeros(numComponents,3);
 for r = 1:numComponents
       componentData(r,1) = str2double(input('Enter A:','s'));
       componentData(r,2) = str2double(input('Enter B:','s'));
       componentData(r,3) = str2double(input('Enter C:','s'));
 end

Note how we pre-size the componentData matrix and then convert each input string to a double using str2double. See input for why the 's' input is used.

However, if you are expecting the user to enter numeric and/or non-numeric data, then you could use a cell array instead

 numComponents = input('Enter Number of Liquid Components:' )
 componentData = cell(numComponents,3);
 for r = 1:numComponents
       componentData{r,1} = input('Enter A:','s');
       componentData{r,2} = input('Enter B:','s');
       componentData{r,3} = input('Enter C:','s');
 end

Try either of the above and see what happens!

I'm trying to get numeric values. For example, if the loop ran twice the code should spit out, A,B,C values for both times the loop ran.

Eg.

 3 4 5
2 4 5

[Sayyid Ferouz]

My main issue is that the loop will only display the last values that were inputted. I need the info in an array

[Geoff Hayes]

Sayyid - use the first example that I have posted above and that will allow you to save the numeric data (from each iteration of the loop) to an array.
