ones

Arguments

x,y

matrices

m1, m2,..

integers

Description

Returns a matrix made of ones.

ones(m1,m2)

returns a (m1,m2) matrix full of ones.

ones(m1,m2,..,mn)

creates a (m1,m2,..,mn) matrix full of ones.

ones(x)

returns a matrix full of ones with the same size that x.

ones(x)

is also valid for x a syslin list.

Remarks

• Note that ones(3) is ones(a) with a=3 i.e it is NOT a 3x3 matrix!

• ones() is equivalent to ones(1,1).

• ones(3,-3) and ones(-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(2,3,2)

repmat(1, [2 4 2])
