I use boundary element method to deal with some dynamic calculation problem. When I calculate time step 12, the total cell number equals 363, one matrix dimension becomes allocate(363*3,363*3). When the size of a matrix exceeds (1000,1000), how can I deal with this issue?

The error is shown as below

    Looks like you have an error in your code. We cannot help you if you don't show it. See [mcve] and [ask]. – Vladimir F Героям слава Nov 09 '17 at 16:47
  • And please copy the error messages here as text, not just picture. It is important, really. If you don't know how to do it, search "copy text from windows command prompt" or similar. you will get links like https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/windows_dos_copy.mspx or https://www.howtogeek.com/howto/windows-vista/copy-to-the-clipboard-from-the-windows-command-prompt/ – Vladimir F Героям слава Nov 09 '17 at 16:48
