How would I take the fprintf statement and values and input into a matrix?

data = fopen('PH.csv');

pH = textscan(data,'%s %d','delimiter',',');

fclose(data);

rows = size(pH{1});

name = pH{1};

pH = pH{2};

for i = 1:rows

     if pH(i) > 7

          acid_base{i} = 'It is a base';

     elseif pH(i) < 7

          acid_base{i} = 'It is an acid';

     else

          acid_base{i} = 'It is neutral';

      end

end

for i = 1:rows

      fprintf('%s - pH: %d \n %s\n',name{i},pH(i),acid_base{i});

end

data = fopen('PH.csv');

pH = textscan(data,'%s %d','delimiter',',');

fclose(data);

rows = size(pH{1});

name = pH{1};

pH = pH{2};

for i = 1:rows

     if pH(i) > 7

          acid_base{i} = 'It is a base';

     elseif pH(i) < 7
          acid_base{i} = 'It is an acid';
     else
          acid_base{i} = 'It is neutral';
      end
  end
  for i = 1:rows
      fprintf('%s - pH: %d \n %s\n',name{i},pH(i),acid_base{i});
  end

What you want to do?

[Collin Noblet]

Instead of displaying the name, pH, and acidity using a fprintf statement, how would I display it in an array?

Answer 1

[Walter Roberson]

Use sprintf to create formatted character vectors that you can store for later use.

Answer 2

[KSSV]

pH = 1:14 ;
S = cell(length(pH),1) ;
for i = 1:length(pH)
    val = pH(i) ;
    if val < 7
        S{i} = sprintf('pH = %f,solution is acidic',val) ;
    elseif val ==7
        S{i} =  sprintf('pH = %f,solution is neutral',val) ;
    elseif val > 7
        S{i} =  sprintf('pH = %f,solution is basic',val) ;
    end
end
