Creating Arrays (colon)

• The colon can be used to generate a sequence of values. Forms:

lowValue : highValue

lowValue : step : highValue

Examples:

1 : 10

1 : 2 : 10

1 : 0.5 : 10

10 : –1 : 1

0 : 0.01 : 0.5

• A sequence of values is an array value.

a = 0 : 2 : 16

b = [1 : 6] / 3

• A sequence of integers can also be used to select a segment of an array.

a(3:6)
