Description
|
|
|
•
|
The Dimension(A) command, where A is a Vector, returns the number of elements in A. If A is a Matrix, two non-negative integers representing the row dimension and the column dimension of A, respectively, are returned.
|
|
|
Dimensions(A) is an alternate form for Dimension(A).
|
|
•
|
The ColumnDimension(A) command, where A is a Matrix, returns the number of columns in A.
|
|
•
|
The RowDimension(A) command, where A is a Matrix, returns the number of rows in A.
