Are the arrows always the same shape? Are they always the same size? Are they always the same angle? If so, use nromxcorr2(). Otherwise search VisionBib for pattern recognition papers and code one up. Even OCR methods would work for an arrow.

Perhaps you should try the Computer Vision System Toolbox. I think it has SURF or SIFT or other methods for doing things like that. Are you going to show us your image? (Try http://snag.gy)
