cs.nju.edu.cntensor. A color image is in fact an order 3 tensor. An image with Hrows and W columns is a tensor with size H W 3: if a color image is stored in the RGB format, it has 3 channels (for R, G and B, respectively), and each channel is a H Wmatrix (second order tensor) that contains the R (or G, or B) values of all pixels.

Electrodynamics - Duke University
webhome.phy.duke.eduFour simple vector equations (or one tensor equation and an asssociated dual) describe the unified electromagnetic field and more or less directly imply the theory of relativity. The discovery and proof that light is an electromagnetic wave and unifies two fields stands to this day as one of the greatest moments in the history of science.

projects.iq.harvard.eduij is the stress tensor and F i the external force per unit volume. Note that these forces are of two types: i) contact forces, due to the pres-sure/stress exerted by abutting faces of neighbor cubes, ii) volume forces, due to external elds, say gravity or electric elds for the case of charged uids.
