scale

Change size of shape by fixed factor

Syntax

scale(shape,factor)

c = scale(shape,factor)

Description

scale(shape,factor) scales the shape by a constant scaling factor and plots the resultant shape.

c = scale(shape,factor) scales the shape by a constant scaling factor and returns a shape object.

Examples

Scale Rectangle Shape

Create a rectangular shape.

r  = antenna.Rectangle;
show(r)
axis equal

Shrink the rectangle by 50%.

scale(r,0.5);

Input Arguments
