Hi,
Quick question: a want to contionally format a variable so that there are 2 decimals for all numbers except for 0; 0 should be 0, not 0.00. What would be the easiest way to do that ?
T = table([1.16666, 2.16666, 3.16666, 0, 0]');
T_names = T.Properties.VariableNames;
y = table2cell(T).';
fid = fopen('test.txt','wt');
fprintf(fid, '%s\n', T_names{:});
fprintf(fid, '%.2f\n', y{:});
fclose(fid);
Thank you,

Hi,
Here is an easy solution with if cond operator:
...
fprintf(fid, '%s\n', T_names{:});
for ii=1:numel(y)
if y{ii}~=0
fprintf(fid, '%.2f\n', y{ii});
else
fprintf(fid, '%1.0f\n', y{ii});
end
end
fclose(fid);

Yes, thank you, but what if I have many variables and I want to contionally format several of them, say variables T.d and T.h ?
a = {'C1', 'A1', 'B1'}'
b = {'C', 'A', 'B'}'
c = {1.1, 2.1, 3.1}'
d = {1.16666, 2.16666, 0}'
e = {'C', 'A', 'B'}'
f = {'C', 'A', 'B'}'
g = {1.1, 2.1, 3.1}'
h = {1.16666, 2.16666, 0}'
T = table(a, b, c, d, e, f, g, h);
T_names = T.Properties.VariableNames;
y = table2cell(T);
fid = fopen('test.txt','wt');
fprintf(fid, '%s;%s;%s;%s;%s;%s;%s;%s;\n', T_names{:});
fprintf(fid, '%s;%s;%.1f;%.2f;%s;%s;%.1f;%.2f;\n', y{:});
fclose(fid);
