repmat
Replicate and tile an array
Syntax
B = repmat(A, siz) B = repmat(A, m) B = repmat(A, m, n,...)
Arguments
- A
- Array of any native type (boolean, numeric, text,..., cells, structures), of any number of dimensions of any sizes. Boolean or numerical sparse matrices are supported.
- m, n, ...
- Positive integers: number of times that
A
must be replicated along the respective dimensions #1, #2, etc.. - siz
- Vector of replication numbers:
siz=[m,n,..]
. - B
- Tiled array or ND-array, of sizes [m*size(A,1), n*size(A,2), ..] or [siz(1)*size(A,1), siz(2)*size(A,2), ..].
Description
repmat(A, m) replicates and tiles
m
× m
copies of A
.
repmat(A, m, n) or
repmat(A, [m, n]) replicates and tiles
m
× n
copies of A
.
repmat(A, m, n, p, ..) is a generalization of repmat(A, m, n).
repmat(…)
extends ones(m,n,..) .*. A
to non-numerical inputs A
.
repmat(…)'s definition can be extended using the overloading mechanism.
