Octave Arrays And Vectors
Description
A vector is an $n$-tuple of numbers. In Octave, we enclose vectors in square brackets
Sage Cell
Code
a = [1 4 5]
Options
Option
We can use a(3) to access the third element in the vector a.
Code
a = [1 2 3 4 5 6 7 8 9 10]
a(3)
Option
We can separate the entries in a vector with commas instead of spaces.
Code
a = [1, 4, 5]
Option
If we separate the entries in a vector with semicolons, we obtain a column vector.
Code
a = [1; 4; 5]
Option
We can also build longer vectors from shorter one.
Code
a = [1 4 5]
b = [a 6 7]
Option
The colon notation can be used as a shortcut to create vectors.
Code
a = 2:10
b = 2:0.6:10
