Using fprintf: string in array is NaN
显示 更早的评论
Hi Everyone,
Please, see my code below. My data.name variable which is a string contains only NaN values when printed.
Any suggestions on how to solve this issue? Thanks in advance.
data.x= [0;1;0;1]
data.y= [1;1;1;1]
data.z= [0;0;0;0]
data.name={'Laura'; 'Caroline'; 'Lynne'; 'Charlie'}
input=[data.x data.y data.z convertCharsToStrings(data.name)];
fmt = repmat(',%.12g',1,size(input,2)); % numeric format for input
fmt = [fmt(2:end),'\n'];
[fid,msg] = fopen('test.csv','wt');
assert(fid>=3,msg)
fprintf(fid,'\n');
fprintf(fid,'\n');
fprintf(fid,fmt,input.');
fclose(fid);

No need to convert data to string:
>> data.x = [0;1;0;1];
>> data.y = [1;1;1;1];
>> data.z = [0;0;0;0];
>> data.name = {'Laura'; 'Caroline'; 'Lynne'; 'Charlie'};
>> tmp = [num2cell([data.x,data.y,data.z]),data.name].';
>> fmt = [repmat('%.12g,',1,3),'%s\n'];
>> fprintf(fmt,tmp{:})
0,1,0,Laura
1,1,0,Caroline
0,1,0,Lynne
1,1,0,Charlie
