A quick test shows that the svn version works with 3.4.2 and 3.4.3-rc0 and plotting the result of the example looks very reasonable. x = linspace(0,1,100)'; y=x.^2+0.1*(2*rand(100,1)-1); z=regdatasmooth (x, y); plot(x, [y z])

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
