Creating Vectors (or one dimensional arrays) in Matlab.
One dimensional array (Vector)
>> X = [1 3 0 -1 5] (press Enter)
ans =
1 3 0 -1 5
It will create a vector with entries 1 3 0 -1 5
>> X (1) (press Enter)
ans =
1
It shows the first element of the vector X.
>> X (2) (press Enter)
ans =
3
It shows the second element of the vector X.
>> X (5) (press Enter)
ans =
5
It shows the fifth element of the vector X.
>> X (1:3) (press Enter)
ans =
1 3 0
It shows the elements from first to third of the vector X.
>> X (2:5) (press Enter)
ans =
3 0 -1
It shows the elements from second to fifth of the vector X.
Size of an array
>> size (X) (press Enter)
ans =
1 5
It shows size of the array X (1 row and 5 columns).
