Indexing Vectors
An array of dimension 1 x N is called a row vector.The elements of such a vector can be accessed using a single index value (also called a subscript). Thus, v (1 ) is the first element of vector v, v (2) is its second element, and so forth. Vectors can be formed in MATLAB by enclosing the elements, separated by spaces or commas, within square brackets.
Example
>> A = [1 2 3 4 5 6] A = 1 2 3 4 5 6
Accessing vector elements
Example
>> A(1) ans = 1 >> A(3) ans = 3 >> A(3) = 6 A = 1 2 6 4 5 6 >> A(3) ans = 6
