zeros - Create array of all zeros
Syntax
B = zeros(n)
B = zeros(m,n)
B
= zeros([m n])
B = zeros(m,n,p,...)
B
= zeros([m n p ...])
B = zeros(size(A))
zeros(m, n,...,classname)
zeros([m,n,...],classname)
Description
B = zeros(n) returns an n-by-n matrix
of zeros. An error message appears if n is not
a scalar.
B = zeros(m,n) or B
= zeros([m n]) returns an m-by-n matrix
of zeros.
B = zeros(m,n,p,...) or B
= zeros([m n p ...]) returns an m-by-n-by-p-by-... array
of zeros.
Note
The size inputs m, n, p, ... should
be nonnegative integers. Negative integers are treated as 0. |
B = zeros(size(A)) returns
an array the same size as A consisting of all zeros.
zeros(m, n,...,classname) or zeros([m,n,...],classname) is
an m-by-n-by-... array of zeros
of data type classname. classname is
a string specifying the data type of the output. classname can
have the following values: 'double', 'single', 'int8', 'uint8', 'int16', 'uint16', 'int32', 'uint32', 'int64',
or 'uint64'.
Example
x = zeros(2,3,'int8');
Remarks
The MATLAB language does not have a dimension statement; MATLAB automatically
allocates storage for matrices. Nevertheless, for large matrices, MATLAB programs
may execute faster if the zeros function is used
to set aside storage for a matrix whose elements are to be generated
one at a time, or a row or column at a time. For example
x = zeros(1,n);
for i = 1:n, x(i) = i; end
