Description:
Create a matrix whose major diagonal element is 1 and other elements are 0.
Syntax:
eye(n1,n2)
Note:
The external library function (See External Library Guide) creates a new matrix according to parameter n1 and parameter n2 that define the dimensions. When only one parameter is present, the function creates a unit matrix of size n.
Parameter:
n1/ n2 |
Positive integers |
Return value:
A sequence
Example:
|
A |
|
1 |
=eye(4,3) |
Create a 4*3 matrix with the length of diagonal line being 1. |
2 |
=eye(3) |
Create a unit matrix of size 3.
