I have two vectors,how can i calculate the standard deviation for each element so i can plot the error bars in the curve.

thank you

One approach:

x = 1:10;                                           % Create Data (Independent Variable)
V1 = randn(1, 10);                                  % Create Data (Row Vectors)
V2 = randn(1, 10);
V12_sd = std([V1; V2]);                             % Standard Deviation
V12_mean = mean([V1; V2]);                          % Mean
figure(1)
errorbar(x, V12_mean, V12_sd)
