Create array of all ones

`X = ones`

`X = ones(n)`

`X = ones(sz1,...,szN)`

`X = ones(sz)`

`X = ones(classname)`

`X = ones(n,classname)`

`X = ones(sz1,...,szN,classname)`

`X = ones(sz,classname)`

`X = ones('like',p)`

`X = ones(n,'like',p)`

`X = ones(sz1,...,szN,'like',p)`

`X = ones(sz,'like',p)`

`X = ones`

returns the scalar `1`

.

`X = ones(`

returns
an `sz1,...,szN`

)`sz1`

-by-...-by-`szN`

array of
ones where `sz1,...,szN`

indicates the size of each
dimension. For example, `ones(2,3)`

returns a 2-by-3
array of ones.

`X = ones(`

returns
a scalar `classname`

)`1`

where `classname`

specifies
the data type. For example, `ones('int8')`

returns
a scalar, 8-bit integer `1`

.

`X = ones(`

returns
an `sz1,...,szN`

,`classname`

)`sz1`

-by-...-by-`szN`

array of
ones of data type `classname`

.

`X = ones('like',`

returns
a scalar `p`

)`1`

with the same data type, sparsity, and
complexity (real or complex) as the numeric variable, `p`

.

`X = ones(`

returns
an `sz1,...,szN`

,'like',`p`

)`sz1`

-by-...-by-`szN`

array of
ones like `p`

.
