So I have to print out a table consisting of two columns of numbers (not integers) and one column containing strings. I try to do the following, and no matter what I do, it gives me either cannot concatenate errors or just outputs incorrectly:
P=[6.5443 871.2282]
c=[6.7469 795.1066]
c1=[6.5472 870.5470 ]
c2=[6.4626 910.2019]
table=[P,c,c1,c2]';
words=['polyfit ';'basis functions';'nlinfit ';'L1 '];
words2=cellstr(words);
stuff={table,words}
fprintf('%6.4f \t %8f \t %s \n',stuff{:})
Output:
  • 6.5443 6.746877 6.547151e+00
  • 6.4626 871.228166 7.951066e+02
  • 870.5470 910.201907 pbnLoal1lsi yin fsf i i tft u n c t i o
Unfortunately, It prints out "table" first for the first 8 times and does not do what I want. Please help

You have to admit that it is not very easy to guess what you want. You have a cell with a (8x1) numerical array and a (4x15) char array.
Then you ask matlab to print two numbers and one string out of it.
I can guess what you want, although I'm not sure why you want to do that in one single command. Why don't you use 4 fprintf commands?

Your code needed a few tweaks and a loop, but now it works:
P=[6.5443 871.2282];
c=[6.7469 795.1066];
c1=[6.5472 870.5470];
c2=[6.4626 910.2019];
table=[P;c;c1;c2];
words={'polyfit';'basis functions';'nlinfit';'L1'};
stuff={table,words};
for k1 = 1:size(words,1);
fprintf('%.4f \t %.4f \t %s \n',stuff{1}(k1,:),char(stuff{2}(k1)))
end
produces:
6.5443 871.2282 polyfit
6.7469 795.1066 basis functions
6.5472 870.5470 nlinfit
6.4626 910.2019 L1
The loop is usually necessary if you have mixed variable types.
