Hi,
I have been using MATLAB R2019b on a laptop with 64-bit Windows 10 system and Intel Core i7-7600U processor, and it worked well.
Just uninstalled it and installed R2020a. However, for the same program to test the new MATLAB version, I now have the following error which never encountered before in all the previous MATLAB versions:
"Error using repmat
Requested 681x3x82x25x2041 (63.7GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to become unresponsive."
Could any one please guide me how to solve this issue? Is there any way not to change my program or input files, but to just modify the MATLAB setting? Many thanks.

Hi Shuya,
How much RAM do you have on your system? Do you have 63.7 GB available memory to load the matrix. Further, the operations on the matrix would require even more RAM.
