shape

shape(X)

X is a scalar/vector/matrix/table.

Return the dimension of a scalar/vector/matrix as a PAIR.

Dimension of a scalar is 1 by 1:

shape 6;
// output: 1:1

s;

Dimension of a vector is the length of the vector by 1:

shape 1 5 3 7 8;
// output: 5:1

Dimension of a matrix:

m=(5 3 1 4 9 10)$3:2;
m;

shape m;
// output: 3 :2

Dimension of a table:

t=table(1 2 3 as x, 4 5 6 as y);
t;

shape t;
// output: 3 :2
