3. SPAC Lab, Stevens Rules for vector and matrix operations 3 Method Each variable is expressed as a Thing It is further expressed by a Place including: a Thing (the variable) an action (the size of the variable [m,n]) [m,n] expresses the action of creating an m by n matrix Remark The size information is abstracted and stored when the value of this variable is first assigned and is updated whenever the variable’s size changes. Basic operations are defined in the sense of matrix operation.
