8. Equally Spaced Arrays

Typing every entry is time consuming for long arrays. If the points are equally spaced this isn't necessary. An alternative method is to use the colon notation [first_value : interval : last_value]

>> a = 1:2:10
a =
     1     3     5     7     9
>>

If the interval is left out MATLAB uses a default interval of 1.

Another way of specifying an equally-spaced array is to use the linspace command. This allows you to specify the number of data points, but not the interval to be used. The notation is:
linspace(first_value, last_value, number_of_values)
If the data for number_of_values is not specified, it is taken as 100.
