[x,y] = transformPointsForward(tform,u,v)
applies the forward transformation of 2-D geometric transformation
tform to the points specified by coordinates
u and v.

[x,y,z] = transformPointsForward(tform,u,v,w)
applies the forward transformation of 3-D geometric transformation
tform to the points specified by coordinates
u, v, and
w.

X = transformPointsForward(tform,U)
applies the forward transformation of tform to the input
coordinate matrix U and returns the coordinate matrix
X. transformPointsForward maps the
kth point
U(k,:) to the point
X(k,:).

For 3-D geometric transformations, tform is an
affine3d object or geometricTransform3d geometric transformation object.

u — x-coordinates of points to be transformed m-by-n or
m-by-n-by-p
numeric array

x-coordinates of points to be transformed, specified as
an m-by-n or
m-by-n-by-p
numeric array. The number of dimensions of u matches
the dimensionality of tform.

Data Types: single | double

v — y-coordinates of points to be transformed m-by-n or
m-by-n-by-p
numeric array

y-coordinates of points to be transformed, specified as
an m-by-n or
m-by-n-by-p
numeric array. The size of v must match the size of
u.

Data Types: single | double

w — z-coordinates of points to be transformed m-by-n-by-p
numeric array

z-coordinates of points to be transformed, specified as
an m-by-n-by-p
numeric array. w is used only when
tform is a 3-D geometric transformation. The size
of w must match the size of
u.

Data Types: single | double

U — Coordinates of points to be transformed l-by-2 or
l-by-3 numeric array

Coordinates of points to be transformed, specified as an
l-by-2 or
l-by-3 numeric array. The number
of columns of U matches the dimensionality of
tform.

The first column lists the x-coordinate of each point
to transform, and the second column lists the
y-coordinate. If tform represents a
3-D geometric transformation, U has size
l-by-3 and the third column lists
the z-coordinate of the points to transform.

x — x-coordinates of points after transformation m-by-n or
m-by-n-by-p
numeric array

x-coordinates of points after transformation, returned
as an m-by-n or
m-by-n-by-p
numeric array. The number of dimensions of x matches
the dimensionality of tform.

Data Types: single | double

y — y-coordinates of points after transformation m-by-n or
m-by-n-by-p
numeric array

y-coordinates of points after transformation, returned
as an m-by-n or
m-by-n-by-p
numeric array. The size of y matches the size of
x.

Data Types: single | double

z — z-coordinates of points after transformation m-by-n-by-p
numeric array

z-coordinates of points after transformation, returned
as an m-by-n-by-p
numeric array. The size of z matches the size of
x.

Data Types: single | double

X — Coordinates of points after transformation numeric array

Coordinates of points after transformation, returned as a numeric array.
The size of X matches the size of
U.

The first column lists the x-coordinate of each point
after transformation, and the second column lists the
y-coordinate. If tform represents a
3-D geometric transformation, the third column lists the
z-coordinate of the points after
transformation.
