# (calc.info)Matrix Functions

11 Vector/Matrix Functions
**************************
Many of the commands described here begin with the `v' prefix. (For
convenience, the shift-`V' prefix is equivalent to `v'.) The commands
usually apply to both plain vectors and matrices; some apply only to
matrices or only to square matrices. If the argument has the wrong
dimensions the operation is left in symbolic form.
Vectors are entered and displayed using `[a,b,c]' notation.
Matrices are vectors of which all elements are vectors of equal length.
(Though none of the standard Calc commands use this concept, a
three-dimensional matrix or rank-3 tensor could be defined as a vector
of matrices, and so on.)
