RESHAPE Reshape Array

Usage

The reshape routine has the following syntax

   y = reshape(x,dims)

where dims is either a vector containing the dimensions of the output, or is a sequence of scalars. In particular, you can use the form

   y = reshape(x,dim1,dim2,...,dimn)

or

   y = reshape(x,[dim1,dim2,...,dimn])

Note that for a reshape to be legal, the output array must have the same number of elements in it as the input array.

Example

Here is an example of a multidimensional array being reshaped into a matrix

--> x = rand(2,2,2)
x = 
  <double>  - size: [2 2 2]
(:,:,1) = 
 
Columns 1 to 2
