Setting default values for plots in Matlab 2014b (OS X 10.10)

I am running a script to plot in Matlab 2014b (OS X 10.10). In the headers I have the command set(groot,'defaultlinelinewidth',2.5); However, it has no effect on my plots. All my plots come out with Linewidth = 0.5. The same script works well in other versions of Matlab. In one of the plots, I tried plot(X,Y,'linewidth',2.5); and it worked fine. Any idea why this is happening? I have more than 20 plots in that script, and I would prefer not to change the code for each plot command. Additionally, I run the commands "get(groot,'default')"

ans =

    defaultFigurePaperPositionMode: 'manual'
             defaultFigurePosition: [360 278 560 420]
            defaultTextInterpreter: 'latex'
              defaultLineLineWidth: 2.5000
             defaultLineMarkerSize: 6
               defaultTextFontSize: 18
               defaultAxesFontSize: 20
r = groot;
r.Children(1).LineWidth

ans =

    0.5000

I really don't understand what is going on. Thanks

Probably need proper capitalization. This works fine for me:

set(groot,'DefaultLineLineWidth',2.5)
plot(1:10)

thanks for your answer. Unfortunately it doesn't work for me

Experienced the same problem. This works for me:

set(0,'defaultLineLineWidth',1.5)
