Maximum Data Set Size For MATLAB Mesh?

I am plotting a waveform as a function of time and space using a MATLAB mesh plot. The number of space steps is 101. The number of time steps is originally 2^14. I get a good plot except for some wraparound of the signal at the window edges. So I doubled my number of time steps to 2^15. When I do this the plots return garbage.

Is there a maximum data set size for mesh plots in MATLAB? Is it depend on the version of MATLAB? Or is it machine dependent?

Generally Matlab will happily create large matrices as long as your computer has enough memory and it is within the 32-bit or 64-bit addressing limits. See http://www.mathworks.com/support/tech-notes/1100/1110.html

If you were hitting the memory cap you would get an out of memory error.

matrix of 2^15*101 ~ 3,200,000 elements (doubles) => ~25 Mb of memory

Your code must have a bug somewhere.
