It is impossible to install without MCR in any documented way, and I even think that this is not legal.
However, there are a few examples, such as Imatest , which managed to do this in some of their earlier versions.
Edit (1)
I almost forgot about MatlabCoder . If you buy it, it can convert your Matlab code directly to c code. But it will not work with some tools, such as image processing.
