size

size(vect|mat)

:: 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 non-zero 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]
