Generating co-efficient of polynomial equation using polyfit with for loop

for n=1:4

res(n,:)=polyfit(fandata.x1,fandata.y1,6);

end

fandata______________

x1 y1 y2 y3 y4

0 420 620 820 1020

10 373 550 727 903

20 340 500 660 820

30 313 460 607 753

40 293 430 567 703

50 273 400 527 653

60 259 378 497 617

70 243 355 467 578

---------------------------------

i need to get coeffiecient of each y1,y2,y3... data polynomial (curve) and to load in 'res' table. So for that i need to iterate y colounm in the above for loop.

How to write the code to loop

Maybe you could convert table fandata to a array. Following is my method.

 A = table2array(fandata); %Convert fandata table to array(matrix) A
 for n=1:4
     res(n,:)=polyfit(A(:,1),A(:,n+1),6);
 end

Worked out!! Thank you
