Syntax
Y=
ones(n) Y
=
ones(m,n) Y = ones([m n]) Y =
ones(d1,d2,d3...) Y = ones([d1 d2 d3...]) Y =
ones(size(A)) ones(m, n,...,classname) ones([m,n,...],classname)
Description
Y = ones(n)
returns an n
-by-n
matrix of 1
s. An error message appears if n
is not a scalar.
Y
returns an
=
ones(m,n) or Y
=
ones([m n])
m
-by-n
matrix of ones.
Y = ones(d1,d2,d3...) or Y
returns an array of
=
ones([d1 d2 d3...])
1
s with dimensions d1
-by-d2
-by-d3
-by-...
.
Y = ones(size(A))
returns an array of 1
s that is the same size as A
.
ones(m, n,...,classname)
or ones([m,n,...],classname)
is an m
-by-n
-by-... array of ones of data type classname
. classname
is a string specifying the data type of the output. classname
can have the following values: 'double'
, 'single'
, 'int8'
, 'uint8'
, 'int16'
, 'uint16'
, 'int32'
, 'uint32'
, 'int64'
, or 'uint64'
.
