How can I plot two different columns in a single matrix without mixing them, using fprintf?

Hi, can you help me please? I'm trying to print two columns. This is my code

b=[1; 2; 3; 4];
c=[b b];
test=fopen('prova.txt','w');
fprintf(test,'%f %d\n', c);
fclose(test);

I'd like to see it this way

1.000000 1
2.000000 2
3.000000 3
4.000000 4

but I get

1.000000 2
3.000000 4
1.000000 2
3.000000 4

Could you please help me?

Thank you very much.

Hello Amal,

After analyzing your code I realized that you have not properly stored the data in c (Wrong Order). You have to understand that fprintf function writes the data column wise and hence store the data in that order itself.

b=[1 2 3 4];
c=[b; b];
test=fopen('prova.txt','w');
fprintf(test,'%f %d\n', c);
fclose(test);

Also Please refer the Documentation of fprintf for more information.
