MATLAB: MATLAB crash when using newer release like R2015b in 32-bit Windows

simulink

I want to know why MATLAB crash for following situation.
  • MATLAB freezes when making simple Simulink models.
  • Cannot save Simulink model.
  • Come across memory allocation error while simulating Simulink model.

If you are using 32-bit Windows, you might come across memory error by using newer version of MATLAB. To identify whether memory issue is related, you can check it by memory command. When you execute memory command, following
- Maximum possible array
- Memory available for all arrays
- Memory used by MATLAB
- Physical Memory (RAM)
If the Maximum possible array is less than 100 MB, the issue is due to out of memory.
On the other hand, there is a restriction for 32-bit Windows that we can use maximum 2GB memory for one application. Also, there is a trend that memory used in MATLAB increase as the version become newer.
R2015b is the last version that can be used in 32bit Windows. We will recommend to use 64-bit Windows to use MATLAB comfortably.
If you cannot prepare 64-bit Windows, try to stop other programs and check whether there is a difference in using MATLAB.
