Hi,

I simply want to combine two variables (mean and sd) into a single variable with the symbol ± in between numbers.

mean = {1,2,3,4,5,6,7,8,9}.';
sd = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9}.';
t = table(mean, sd);
t.output =  {'1±0.1', '2±0.2', '3±0.3', '4±0.4', '5±0.5', '6±0.6', '7±0.7', '8±0.8', '9±0.9'}.';

The desired output is t.output.

Thank you,

You should rename your value called mean as something that is not already a function name.

    meanval = {1,2,3,4,5,6,7,8,9}.';
    sd = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9}.';
    t = {strcat(num2str(cell2mat(meanval)),'±',num2str(cell2mat(sd)))};
