Student[LinearAlgebra][Dimension] - determine the dimension of a Matrix or a Vector
Student[LinearAlgebra][ColumnDimension] - determine the column dimension of a Matrix
Student[LinearAlgebra][RowDimension] - determine the row dimension of a Matrix
Calling Sequence
Dimension(A)
RowDimension(A)
ColumnDimension(A)
Parameters
A
-
Matrix or Vector
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.
