fprintf using a for loop
显示 更早的评论
Hello,
I seem to be having trouble figuring out how to make a table using fprintf using a for loop.
I currently have one cell array and 3 row vectors defined as such:
C = {’a’, ’bb’, ’ccc’, ’dddd’, ’eeeee’};
x = [6.715, -12.075, 7.172, 16.302, 4.889];
y = [-134.98869, 303.49235, 72.54042, -6.30549, 71.47429];
z = [14380, 0.00325, -7549, 13700, -0.00017];
My task is to create a table using fprintf that looks exactly like the following:
x C y C z
---------------------------------------------------
6.715 a -134.98869 a +1.438E+004
-12.075 bb 303.49235 bb +3.250E-003
7.172 ccc 72.54042 ccc -7.549E+003
16.302 dddd -6.30549 dddd +1.370E+004
4.889 eeeee 71.47429 eeeee -1.700E-004
Any help would be appreciated. Thanks.

Well, after the header lines, when you get to line #K, you would be wanting to emit
x(K), C{K}, y(K), C{K}, z(K)
Everything beyond that is no longer a difficulty with using fprintf() in "for" loop, and is instead a difficulty in using fprintf() to emit numbers in particular formats, occupying particular number of columns, and having particular alignments.
I will give you a hint: experiment with %5s and %-5s formats when you are printing out C{K}.

Remove the statements
x=x(i)
y=y(i)
C=C{i}
z=z(i)
as they are going to wipe out the variables you are trying to print out!
The only change I would make to
fprintf('%7.3f %5s %9.5f %-5s %5.3e',x(i), C{i}, y(i), C{i}, z(i))
is
fprintf('%7.3f %5s %9.5f %-5s %5.3e\n',x(i), C{i}, y(i), C{i}, z(i))
