As you may know, entrinsic functions are not outputted during the code generation process. Are there alternatives to these functions/ and or solutions to this problem? My code generation error report is shown below :
I am surprised that I can't output size and rgb2gray either. Since these are essential to my program, I cannot avoid them.
Help will be much appreciated!

I guess you will need to write them yourself. I'm not sure why they exclude those particular functions though.

I understand that I may be able to implement rgb2gray and size , but imread seems like a behemoth of a task to implement. Is there anyone who has already worked on this?

You're right, for arbitrary images of any possible format. However if you know the format and it's simple, then you can probably use fread() to read in a 2D array. You could then convert it to color if needed.
