Convert matrix to grayscale image
G = mat2gray(M) G = mat2gray(M, [mmin, mmax])
[mmin, mmax]
is the values in
M
that correspond to
0.0
and
1.0
in
G
. The elements in
M
which is lower than
mmin
will be converted to
0.0
, and greater than
mmax
will be converted to
1.0
.mat2gray(M,[mmin, mmax])
converts the matrix
M
to the double precision image. The output matrix
contains values in the range [0.0, 1.0]
.
mmin
and mmax
are the values in
M
that correspond to 0.0 and 1.0 in the output
image.
When [mmin, mmax]
is not specified,
minimum
and maximum
of
M
are the values in M
that
correspond to 0.0 and 1.0 in the output image.
