inserting +- (i.e. \pm) between two numbers in matlab

I want to insert the symbol +- (\pm) between x and y in table created in matlab

x = (1:1:5)';
y = x*5/100;
table = [x y]

So, that the output is 

1.0000 +/- 0.0500
2.0000 +/- 0.1000
3.0000 +/- 0.1500
4.0000 +/- 0.2000
5.0000 +/- 0.2500

If we can also write the minus exactly below plus.

fprintf(['%0.2f ' char(177) ' %0.2f\n'], [x;y]);

You can use unicode characters in MATLAB. The following works:

>> fprintf('%f ± %f\n', table.')
1.000000 ± 0.050000
2.000000 ± 0.100000
3.000000 ± 0.150000
4.000000 ± 0.200000
5.000000 ± 0.250000

Note that fprintf cycles through all the elements of the input matrix in storage order (down the first column first). So it was necessary to transpose the data array (table.') to print it in one command.

This works for printing to file as well on MacOS:

f = fopen('mytextfile.txt','wt');
fprintf(f,'%f ± %f\n', table.');
fclose(f);

With output as a text file use the format spec for fprintf such as

FileID=fopen('FileName.txt','w');

fprintf(FileID,['%1.4f ',177,' %1.4f\n'],[x';y'])
