MATLAB reshape function
Reshape matrix or array.
reshape(A, ...)
A |
matrix or array containing the original data |
... |
numeric dimensions for the result |
In the first example below, an m-by-n matrix is created whose
elements are taken column-wise from A. An error occurs if A
does not have m*n elements.
In the second example below, an n-dimensional array with the same
elements as A but reshaped to have the size
m-by-n-by-p. The product of the specified dimensions
must be the same as prod(size(A)).
In the third example below, 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)).
Returns matrix (or array) of requested dimensions containing the elements
of A.
