How can I get the sprintf function to work for a cell array and a matrix?

I am writing a code in which I need to use the sprintf function to display the output values. The output values include 2 cell arrays and 5 matrices. For whatever reason I keep getting this error:
Error using sprintf
Function is not defined for 'cell' inputs.
This is the code I am currently using:
output(2)= {sprintf('%s \t %s \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f', probe_label, gene_label, [dtAm], [dtAstd]', [dtBm], [dtBstd]', [dtAB], [dt_pval_sig])};
probe_label and gene_label are the cell arrays and the rest are matrices.

You have to convert them with char to use sprintf and its friends:
probe_label = {'abc' 'def' 'ghi' 'jkl'};
gene_label = {'mno' 'pqr' 'stu' 'vwx'};
[dtAm, dtAstd, dtBm, dtBstd, dtAB, dt_pval_sig] = deal(rand(4,1), rand(1,4), rand(4,1), rand(1,4), rand(1,4), rand(1,4));
for k1 = 1:size(probe_label,2)
output{k1,:} = sprintf('%s \t %s \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f', char(probe_label(k1)), char(gene_label(k1)), dtAm(k1), dtAstd(k1), dtBm(k1), dtBstd(k1), dtAB(k1), dt_pval_sig(k1));
end
I created the data, but this code should work with your data without modification (I hope).

Your numeric data aren’t cells. Change the ‘output’ assignment to:
output{k1,:} = sprintf('%s \t %s \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f \t %.3f', probe_label{k1}, gene_label{k1}, dtAm(k1), dtAstd(k1), dtBm(k1), dtBstd(k1), dtAB(k1), dt_pval_sig(k1));
and it should work
I didn’t test this change specifically, but it is only a minor variation on my original code. Note that only ‘probe_label{k1}’ and ‘gene_label{k1}’ have the curly-braces ‘{}’ cell reference, while your numeric arrays have standard parentheses ‘()’ array references. The referencing conventions can be a bit difficult to understand until you work with them.
