reshape - Reshape array
Syntax
B = reshape(A,m,n)
B = reshape(A,m,n,p,...)
B
= reshape(A,[m n p ...])
B = reshape(A,...,[],...)
B = reshape(A,siz)
Description
B = reshape(A,m,n) returns
the m-by-n matrix B whose
elements are taken column-wise from A. An error
results if A does not have m*n elements.
B = reshape(A,m,n,p,...) or B
= reshape(A,[m n p ...]) returns an n-dimensional array
with the same elements as A but reshaped to have
the size m-by-n-by-p-by-....
The product of the specified dimensions, m*n*p*...,
must be the same as prod(size(A)).
B = reshape(A,...,[],...) calculates
the length of the dimension represented by the placeholder [],
such that the product of the dimensions equals prod(size(A)).
The value of prod(size(A)) must be evenly divisible
by the product of the specified dimensions. You can use only one occurrence
of [].
B = reshape(A,siz) returns
an n-dimensional array with the same elements as A,
but reshaped to siz, a vector representing the
dimensions of the reshaped array. The quantity prod(siz) must
be the same as prod(size(A)).
Examples
Reshape a 3-by-4 matrix
into a 2-by-6 matrix.
A =
1 4 7 10
2 5 8 11
3 6 9 12
B = reshape(A,2,6)
B =
1 3 5 7 9 11
2 4 6 8 10 12
B = reshape(A,2,[])
B =
1 3 5 7 9 11
2 4 6 8 10 12See Also
