problem with error bar

Hi. I want to use errorbar(x,y,std) to get the error bar. I was wondering if x and y are vectors with 10 data point each. how do I write the code for std to have the same matching (10X1) dimension. Thanks

e = std(y)*ones(size(y));

As in:

x = 1:10;

y = randn(10,1);

e = std(y)*ones(10,1);

errorbar(x,y,e)
