 size(vectmat)

:: A list containing the number of elements of the given vector,
[size of vect] ,
or a list containing row size and column size of the given matrix,
[row size of mat, column size of mat] .
 return

list
 vect

vector
 mat

matrix

Return a list consisting of the dimension of the vector vect,
or a list consisting of the row size and column size of the matrix
matrix.

Use
length() for the size of list, and
nmono() for the number of monomials with nonzero coefficients
in a rational expression.
[0] A = newvect(4);
[ 0 0 0 0 ]
[1] size(A);
[4]
[2] B = newmat(2,3,[[1,2,3],[4,5,6]]);
[ 1 2 3 ]
[ 4 5 6 ]
[3] size(B);
[2,3]
