How do you rotate datetick labels?

I have a plot that spans a little over the course of an entire day. I need to label the x axis in 30 minute increments, using the datetick function. I have already been able to figure out how to do that, but once I do, all of the labels are bunched up on one another. I need to rotate my datetick labels 45-90 degrees. I've found various articles talking about this, but have not had any luck implementing them in to my code.

[Mahabub Alam]

startDate = datenum('02-01-1962')

endDate = datenum('11-15-2012')

xData = linspace(startDate,endDate,50)

stem(xData,rand(1,50))

set(gca,'XTickLabelRotation',45)

datetick('x','yyyy','keeplimits')

Note: I do not know whether it is relevant to answer this questions now.

Indeed it probably is not, as MATLAB R2014b introduced datetime, which among other things makes plotting much nicer than datenum/datetick.

startDate = datetime(1962,2,1)
endDate = datetime(2012,11,15)
xData = linspace(startDate,endDate,50)
stem(xData,rand(1,50))
set(gca,'XTickLabelRotation',45)
