Reduce the size of MCR installation

Dear Matlab team,

Could you let me know how to create an MCR installation directory with minimum space. We do not need to use JVM or GUI or CUDA and only use specific toolboxes. Is there a way we can create such a bare minimum directory specific to our application?

Thank you very much for your help! Best, Nagesh

There is no way to reduce the size of MCR installation. The MATLAB runtime architecture requires all the files included.

The R2019a_win64.zip had 1.9 GB. The R2020a_Update_4_win64.zip has 2.6 GB, where are we going to end up with?

This becomes an unacceptable situation. I need to ask my colleagues and customers to download > 2 GB twice a year and unpack it to find an exe... What makes the runtimes that big?

Thanks

Please refer to https://www.mathworks.com/matlabcentral/answers/101332-why-is-matlab-runtime-so-large for more details.

Boss-mode on: We users are not interessed in why it is so big, we want to reduce the size.

Clearly a very large part of the now 850Mb is unnecessary when you compile something like a poket calculator as stand alone.

This problem is known for years, it would be nice if there would be a way to exclude not needed libraries.

Yes, we users want it to be smaller and faster up on loading!

My 2023 version is getting 1.2GB!
