Matrices are entered by enclosing the values in [ ]. Each item in a row is
separated by a , and each row is separated by a
;.
entering [1,2] will produce the 1 by 2 matrix
[1 2]
entering [1,2;3,4] will produce the 2*2 matrix
[1 2]
[3 4]
entering [1;2] will produce the 2*1 matrix
[1]
[2]
The identity matrix can be entered using the function eye
with the size of the matrix as the parameter.
A zero filled matrix can be entered using the zeros
function. This accepts either one parameter to produce a square matrix or two to produce a rectangular matrix.
A one filled matrix can be entered using the ONES function. This accepts either one parameter to produce a square matrix or two to produce a rectangular matrix.
A one dimensional matrix containing a series of numbers can be created using the colon operator either with the form
start : end
start : increment : end
e.g
2:9 = [2,3,4,5,6,7,8,9]
2:2:8 = [2,4,6,8]
