CODEGEN is the command-line way, CODER is the graphical user interface. It's the same technology "under the hood". I expect "codegen" and "coder" to generate the same code if you are using all the same options.

Hi Rajesh,

just to confirm: I guess you invoke coder by

coder -build pca.prj

instead of "-new"? I just gave it another try with a larger project, and apart from the new build date, the generated codes were identical ...

What kind of differences in the code do you see?

Hi Mike,

yesterday when i was going through my code realized a different. when i give "coder -new pca.prj " its generating c code. and while i'm giving codegen -c pca it's generating a mex code.. . and then i created a mex code using coder -new pca.prj, both are matching. . .
