zeros

null matrix

Syntax

y=zeros(m1,m2,...)
y=zeros(x)
y=zeros()

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 null matrix. By default the returned matrix is of double precision floating point type but a given type can be precised in the type argument.

zeros(m1,m2,..,mn)

creates a (m1,m2,..,mn) null matrix.

zeros(m1,m2,..,mn,type)

returns a (m1,m2,..,mn) null matrix with type given by type. In the case of boolean type the matrix is filled with %F value.

zeros(x)

returns a null matrix with the same size as x.

zeros(m1,m2,..,mn,type)

returns a null matrix with the same size as x and type given by type. In the case of boolean type the matrix is filled with %F value.

zeros(x)

is also valid for x a syslin list.

Remarks

repmat(1, sizes) can be used to generate an array of zeros with sizes=[m1 m2 ..] given as a vector.

Examples

zeros(3)
zeros(3,3)
zeros(3,3,"uint8")
zeros(3,3,"boolean")
zeros(2,3,2)

repmat(1, [2 4 2])
