The syntax of the Octave function is a follows:

Variable = [x11, x12, ..., x1n; x21, x22, ..., x2n; xm1, xm2, ..., xmn ]

Where m is the number of rows and n is the number of columns in a m x n matrix.

Matrices and arrays are entered in square brackets, []. Row arrays can be defined using either commas or spaces. Columns are defined by semicolons to separate the elements.

Example of a single row.

>> A = [1, 2, 3, 4]
A =
    1   2   3   4

Example of a single column.

>> B = [1; 2; 3; 4]
B = 
   1
   2
   3
   4

Example of a 3 x 4 matrix.

>> C = [ 1 2 3 4; 5 6 7 8; 9 10 11 12]
C =
   1    2    3    4
   5    6    7    8
   9   10   11   12
