traceSpiral

Create even-sided polygon trace in spiral form

Since R2021b

Description

Use the traceSpiral object to create an even-sided polygon trace such as a square, hexagon, octagon, decagon, or a circle in a spiral form.

Creation

Syntax

trace = traceSpiral

trace = traceSpiral(Name=Value)

Description

trace = traceSpiral creates a square spiral trace. The spiral trace is centered at the origin on the X-Y plane.

trace = traceSpiral(Name=Value) sets Properties using one or more name-value arguments. For example, traceSpiral(ReferencePoint=[1 1]) creates a spiral trace with the reference point [1 1]. Properties not specified retain their default values.

Properties

Name — Name of spiral trace

'myspiral' (default) | character vector | string scalar

Name of the spiral trace, specified as a character vector or a string scalar.

Example: trace = traceSpiral(Name="spiraltrace1")

Data Types: char | string

ReferencePoint — Point of reference of spiral trace

[0 0] (default) | two-element vector

Point of reference of the spiral trace in Cartesian coordinates, specified as a two-element vector. Use the reference point to modify the shape from its initial position.

Example: trace = traceSpiral(ReferencePoint=[1 1])

Data Types: double

InnerDiameter — Inner diameter of spiral trace

0.0040 (default) | positive scalar

Inner diameter of the spiral trace in meters, specified as a positive scalar. If the polygon is a square, the inner diameter is the distance between the innermost vertex and the midpoint of the opposite side of the inner square. For all other shapes, the value is the distance between the innermost vertex and the opposite vertex of the inner turn.

Example: trace = traceSpiral(InnerDiameter=0.0015)

Data Types: double

TraceWidth — Width of spiral trace

0.0020 (default) | positive scalar

Width of the spiral trace in meters, specified as a positive scalar.

Example: trace = traceSpiral(TraceWidth=0.0050)

Data Types: double

Spacing — Distance between traces of spiral

5.0000e-04 (default) | positive scalar

Distance between the traces of the spiral in meters, specified as a positive scalar. For a square spiral trace, the spacing is the gap between the flat edges of adjacent turns. For all other shapes, the spacing is the gap between vertices of adjacent turns.

Example: trace = traceSpiral(Spacing=6.0000e-04)

Data Types: double

NumTurns — Number of turns in spiral

4 (default) | positive scalar

Number of turns in the spiral, specified as a positive scalar.

Example: trace = traceSpiral(NumTurns=6)

Data Types: double

NumSides — Number of sides in each turn

4 (default) | positive, even scalar

Number of sides in each turn of the spiral based on the polygon, specified as a positive, even scalar. The minimum number of sides is 4 and the maximum number is 10. If the number exceeds 10, then the shape is a circle.

Example: trace = traceSpiral(NumSides=6)

Data Types: double
