zeros

Arguments

x,y

matrices

m1, m2,..

integers

Description

Creates matrix of zeros (same as 0*ones).

zeros(m1,m2)

for an (m1,m2) matrix.

zeros(m1,m2,..,mn)

creates a (m1,m2,..,mn) matrix filled with zeros

zeros(A)

for a matrix of same size of A.

zeros(3)

is zeros(a) with a=3 i.e it is NOT a 3x3 matrix!

zeros()

returns a single zero

repmat(0, sizes) can be used to generate an array of zeros with sizes=[m1 m2 ..] given as a vector.

If x is a syslin list (linear system in state-space or transfer form), zeros(x) is also valid and returns a zero matrix.

Examples

zeros(3)
zeros(3,3)
zeros(2,3,2)

repmat(0, [2 4 2])
