Update: This problem turned out to be an intall issue. My app runs on some of our boxes but not others. Thanks all!
When using Plot (Xarray, Yarray, LineStyle); Matlab cores when the array length exceeds a couple thousand elements.
This may be a problem/bug in R2011b that was fixed in 2012.
What are the data limits Matlab can plot?
Can one determine programmatically the largest dimension of the X and Y data arrays that plot can handle?
What constrains the maximum length of X and Y data arrays that can be plotted (Memory, pixels, graphics card and/or licensed version of Matlab ...)?
Is DSPLOT available in Matlab R2011b? If so, what's its API?

I think Walter meant that he would like to see the exact output of the command size(Yarray). This output would always be a vector of length at least 2 as in the following
>> Yarray=rand(2004,1); size(Yarray)
ans =
2004 1
In particular, are we definitely talking about vector inputs? Additionally, what is the output of
>> memory

According to my web search, DSPLOT has never been a stock MATLAB function, but there is a DSPLOT on the File Exchange,
