Scale, ScaleX, ScaleY, ScaleZ

Scaling factors

MuPAD® notebooks will be removed in a future release. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Scale defines the scaling factors used by plot::Scale2d and plot::Scale3d.

ScaleX etc. correspond to the factors in the single coordinate directions.

The scaling objects plot::Scale2d and plot::Scale3d apply the scaling transformation with the matrix A = diag(sx, sy) in 2D and A = diag(sx, sy, sz) in 3D, respectively.

Scale is the list [sx, sy] resp. [sx, sy, sz] of the scaling factors. The attributes ScaleX etc. correspond to sx etc.

These attributes can be animated.


Example 1

We start with a 2D circle:

c := plot::Circle2d(3, [3, 3]):

We apply a scaling transformation:

S := plot::Scale2d([2, 3], c):
plot(c, S):

The scaling factors are stored as the Scale attribute in the scaling object S:

S::Scale, S::ScaleX, S::ScaleY

We change the scaling factors:

S::Scale := [-2, -3]:
plot(c, S):

delete c, S:
