help me....

error>>

??? Error using ==> fprintf
Function is not defined for 'cell' inputs.

Error in ==> earth3 at 53
fprintf(fid,'%s' , sort{1,3});


My code>>


sort{1,1} = date;
sort{1,2} = time;
sort{1,3} = num2cell(mega);fid = fopen('earth2.txt');
Earth = textscan(fid,'%s %s %f %s %s %s');
fclose(fid);
date = Earth{1};
time = Earth{2};
mega = Earth{3}; %ascending power
wi = Earth{4};
gy = Earth{5};
area = Earth{6};

(array....)

sort{1,1} = date;
sort{1,2} = time;
sort{1,3} = num2cell(mega);
fid = fopen('earth_new.txt','wt');
fprintf(fid,'%s', sort{1,3});
fclose(fid);

-----------------
use sprintf??

Hi Kwon,

In this line:

sort{1,3} = num2cell(mega);

you are assigning a cell to sort{1,3}, but in your fprintf, you are writing it as a string by saying %s. This is why you get the error. If mega is of type double, then you could say something like:

fprintf(fid,'%6.4f',mega);

If it is an integer, then

fprintf(fid,'%d',mega);

which all mean that you can directly input your variable. You should only be careful about what you put after the percent sign.
