Any version is acceptable, mainly 20 12a or 20 12b. Some programs in the new version are different from the old version, but the impact is not great. There is also a 20 13 version, but the cracked version is hard to find.

Therefore, it is recommended to use 20 12, and the installation package of 20 12b is more than twice that of 20 12a. If it is too big, use.

Toolboxes are usually loaded. When we use matlab, we all use programs written by others. Those programs will call some toolboxes. Different activation codes will cause you to install different toolboxes. If a toolbox is lost, it can be downloaded and inserted.
