Strange Behavior of Version

Hello,

I am using matlab for study purpose. I have standalone version installed in my desktop, and when I am out of home, I use the online version. Today I experienced a peculiar error which is "computer('arch')" is showing my computer version as Linux 64 bit while I am having Win 10 64 bit installed in my laptop. I couldn't find any documentation on such a problem. Hence I am requesting the exparts if there is something can be done to resolve it. Thank you in advance.

Are you running that in MATLAB Online or in the version you have installed locally on your Windows machine? When I run in MATLAB Online or through MATLAB Answers computer correctly indicates MATLAB is running on a Linux machine.

[str,maxsize,endian] = computer

str = 'GLNXA64'

maxsize = 2.8147e+14

endian = 'L'

Hello Steven,

Thank you for your response. Yes I am running it in Matlab online. And the problem is: I had a simulink protected model to run. but while I was trying to load it in Matlab online it said that the protected model is being created with WIN64 version so it can't be run in Matlab online. So, I checked with the function 'computer', and the result was as I sent.

Hence my question is, is it possible to run such protected files in Matlab online even if they are created in different platform?

I see in the documentation that protected models permitted different kinds of execution effective in different releases. I see that execution in Normal simulation mode (no code generation required) became available for models created in R2018b or later. The implication would be that any model older than that would have been protected to work only through code generation, and a code-generated version would be platform specific I suspect. This does not promise that new enough versions that permit simulation are not platform specific: I have no information about that at the moment... but versions older than do not appear to have any chance of platform independence if I am reading the document correctly.

Hi Walter,

Thank you for the reply. I suspected that too but wasn't so sure. Yeah the model was created with 2015a. It's pretty old actually. And also it generates code when I run in stand alone installed Matlab. Thank you once again!! Have a nice day!
