problem printing double format values
显示 更早的评论
I am unable to print the values in double format, suppose if I have a value b=0.394944961213358 [1x1 double] it shows ??? Undefined function or method 'fprinf' for input arguments of type 'char'.
How can I round it to first four decimal values( as 0.3949) and print it to a file.
Thanks Ram

The function name is fprintf not fprinf
fprintf(fid, '%.4f', b)

In response to the Comment you added to your question:
%before the loop
fid = fopen('YourOutputFile.txt', 'wt');
%inside the loop
fprint(fid, 'i = %d\nb = %.4f\n', i, b);
%after the loop
fclose(fid);
