Is Matlab 2022a compatible with 2021a?

Is 2022a compatible with 2021a

Answer 1

[Walter Roberson]

There are function calls available in the older version that are not available in the newer version, and there are functions that produce different results in the newer version.

So if the required answer must be either Yes or No, then the answer would have to be No.

In what sense? They can both be installed on your computer at the same time, and you can run either of them without problem. Of course if, in your code, you used a function newly introduced in a newer version of MATLAB, it won't be able to be used in an older version (created before that function was introduced) obviously.

In the sense that I want to open a simulink file that was created using the 2021a version

[Image Analyst]

I don't have Simulink but I'm very confident that would work. In the slight chance they removed a deprecated function then you may have to make a slight adaptation to your model but I doubt that would be the case. You can always call the sales team if you want to double check before you buy the new version.

Ok thank you.

One of the math function blocks was removed. You should be able to open systems that use the blocks but you will not be able to add more blocks of the same type unless you know the special setting.

Libraries were rearranged in R2021b so some kinds of models cannot be exported for use in previous versions. I do not recall at the moment whether it was Mechanical or Electrical that was affected.
