I have to write a function which takes as inputs the size of the camera screen HxW, the size of the canvas MxN and the coordinates of the points with respect to the camera screen and returns as output the coordinates of the points with respect to the image canvas (pixels). My problem is that I really don’t know from where to start and any tip would be really appreciated.

Start from scale i think

This sounds like a job for interp1.

Start with writing the function line, which defines inputs and outputs. Explain clearly, what "the coordinates of the points with respect to the camera screen" means - in valid Matlab syntax.
