What is the problem in my for loops?

function tabulatedata()

m = input('Enter m: ');  
n = input('Enter n: ');
p = input('Enter p: ');
fprintf('\nColumn 1\Column 2\n');

for i = 0:n:m
      for j  = 0:m/n
          a = (2.^(j))*p;
          fprintf('%3.2f\t\t\t', i);
          fprintf('%3.2f\n', a); 
      end 
  end

end

We input m = 12, n = 2, p=100

Output:

Column1 Column 2

0.00 100.00

2.00 200.00

4.00 400.00

6.00 800.00

8.00 1600.00

10.00 3200.00

12.00 6400.00

I cannot get the correct output.

You don't need any loops:

m = 12;  
n = 2;   
p = 100; 
v = 0:n:m;
a = 2.^(v./2)*p;
fprintf('%3.2f\t\t\t%3.2f\n', [v;a]);

0.00			100.00
2.00			200.00
4.00			400.00
6.00			800.00
8.00			1600.00
10.00			3200.00
12.00			6400.00

function tabulatedata()

m = input('Enter m: ');  
n = input('Enter n: ');
p = input('Enter p: ');
fprintf('\nColumn 1\Column 2\n');

for i = 0:n:m
      for j  = 0:m/n
          a = (2.^(j))*p;
          fprintf('%3.2f\t\t\t %3.2f\n', i,a);          
      end 
  end

end

Thanks for you answer but Im still gettting a wrong output.

[KSSV]

function tabulatedata()

m = input('Enter m: ');
n = input('Enter n: ');
p = input('Enter p: ');
fprintf('Column 1    Column 2\n');


for j  = 0:m/n
    for i = 0:n:m
        a = (2.^(j))*p;
        fprintf('%3.2f\t\t\t %3.2f\n', i,a);
    end
end

end

Do you know how to solve this problem?

[Walter Roberson]

What problem? You said you do not get the right output, but you do not tell us what output you expect instead.

You don't need nested loops:

m = 12;  
n = 2;   
p = 100; 
fprintf('\nColumn 1\t\tColumn 2\n');

for i = 0:n:m
    a = 2.^(i/2)*p;
    fprintf('%3.2f\t\t\t', i);
    fprintf('%3.2f\n', a);
end

Output:

Column 1 Column 2

0.00 100.00

2.00 200.00

4.00 400.00

6.00 800.00

8.00 1600.00

10.00 3200.00

12.00 6400.00

Thank you so much.

You're welcome. BTW @Stephen Cobeldick's answer is clearly better. Feel free to unaccept my answer and choose @Stephen Cobeldick's answer. I won't take offence. :)
