slash for more information.
A=[10;21];B=[3;5];
A \ B
/ Ordinary scalar division, or right matrix division. For matrices, A/B is essentially
equivalent to A*inv(B) . Type help slash for more information.
* Scalar or matrix multiplication. See the online help for mtimes .
. Not a true MATLAB operator. Used in conjunction witharithmetic operators to
force element-by-element operations on arrays. Also used to access fields of a struc-
ture array.
