Hi guys,

Some help appreciated here. Basically i have a 2d Array of size 1000x1000. I use my initial data to plot using contourf, and things worked out beautifully.

So I process the data and tried plotting it again but Matlab hangs while it is suppose to plot (Pardon the jet(128) yet I use 64 after). I tried both 64 as well or both 128 but still have the same issue.

As you can see, I successfully processed the data but it somehow got stuck at the plotting of the data. When i commented the contourf, the program manage to proceed to the end. The data is completed with all 1000x1000 values in there. I even updated my graphic card driver in case that's the issue. Any idea what could have gone wrong? Is the data size too big? Or the fluctuations in values causes the limitation.

Thanks in advance.

Best regards, Tonny
