ones
matrix made of ones
Syntax
y=ones(m1,m2,...) y=ones(x) y=ones()
Arguments
- x,y
matrices
- m1, m2,..
integers
- type
optional character string: 'double', 'boolean', 'int8', 'uint8', 'int16', 'uint16', 'int32', 'uint32', 'int64', or 'uint64'.
Description
Returns a matrix made of ones. By default the returned matrix is of double precision floating point type but a given type can be precised in the typeargument.
- ones(m1,m2,..,mn)
creates a
(m1,m2,..,mn)
matrix full of ones.- ones(m1,m2,..,mn,type)
returns a
(m1,m2,..,mn)
matrix made of ones with type given bytype
. In the case of boolean type the matrix is filled with%T
value.- ones(x)
returns a matrix full of ones with the same size as
x
.- ones(x,type)
returns a matrix full of ones with the same size as
x
and type given bytype
. In the case of boolean type the matrix is filled with%T
value.- ones(x)
is also valid for
x
asyslin
list.
Remarks
Note that
ones(3)
isones(a)
witha=3
i.e it is NOT a 3x3 matrix!ones() is equivalent to ones(1,1).
ones(3,-3)
andones(-3,-3)
both return an empty matrix.
repmat(1, sizes) can be used to generate an array of ones with
sizes=[m1 m2 ..] given as a vector. |
Examples
ones(3) ones(3,3) ones(3,3,"uint8") ones(3,3,"boolean") ones(2,3,2) repmat(1, [2 4 2])
