unigrid

Uniform grid

Syntax

Grid = unigrid(StartValue,Step,EndValue)
Grid = unigrid(StartValue,Step,EndValue,IntervalType)


Description

Grid = unigrid(StartValue,Step,EndValue) returns a uniformly sampled grid from the closed interval [StartValue,EndValue], starting from StartValue. Step specifies the step size. This syntax is the same as calling StartValue:Step:EndValue.

Grid = unigrid(StartValue,Step,EndValue,IntervalType) specifies whether the interval is closed, or semi-open. Valid values of IntervalType are '[]' (default), and '[)'. Specifying a closed interval does not always cause Grid to contain the value EndValue. The inclusion of EndValue in a closed interval also depends on the step size Step.

Examples

Create Uniform Grids

Create a uniform closed interval grid with a positive increment.

grid = unigrid(0,0.1,1);
grid(1)

ans = 0

grid(end)

ans = 1

Note that grid(1) = 0 and grid(end) = 1.

Create a uniform grid with a semi-open interval.

grid = unigrid(0,0.1,1,'[)');
grid(1)

ans = 0

grid(end)

ans = 0.9000

In this case, grid(end) = 0.9

Create a decreasing grid with a semi-open interval.

grid = unigrid(1,-0.2,0,'[)')

grid = 1×5

    1.0000    0.8000    0.6000    0.4000    0.2000
