errorbar plot for log y scale

ERRORBARLOGY Show the vertical errorbar line in log y scale plot when the data error is larger than data itself.

Matlab buidin ERRORBAR does not plot the vertical errobar line in a log y scale plot when data error is larger than data itself. See the screenshot for comparion.

Example:
x = logspace(1,3,20);
y = 5*(1 + 0.5*(rand(1,20)-0.5)).*x.^(-2);
y_err(1:13) = y(1:13)/2;
y_err(14:20) = y(14:end)*5;
errorbar(x,y,y_err,'o');
