Symmetrical error bars for logarithmic Y-axis.
errorbarlog(X,Y,E,...) plots the graph of vector X vs. vector Y with
a logarithmic Y-axis, using symmetrical bars about the data points, ie:
the bars are such that Y is the geometric mean (instead of arithmetic
mean) of the lower and upper bars. The total length of the error bar is
errorbarlog has the same syntax as the original Matlab's ERRORBAR
function. The only difference is that while ERRORBAR displays the bars
symmetrically for a linear Y-axis (ie: Y is the arithmetic mean of
the lower and upper bars), errorbarlog displays them symmetrically
for a logarithmic Y-axis.
y=5*(1 + 0.5*(rand(1,20)-0.5)).*x.^(-2);
