RESHAPE RESHAPE Reshape An Array

Usage

Reshapes an array from one size to another. Two seperate 
syntaxes are possible.  The first syntax specifies the array 
dimensions as a sequence of scalar dimensions:

   y = reshape(x,d1,d2,...,dn).

The resulting array has the given dimensions, and is filled with
the contents of x.  The type of y is the same as x.  
The second syntax specifies the array dimensions as a vector,
where each element in the vector specifies a dimension length:

   y = reshape(x,[d1,d2,...,dn]).

This syntax is more convenient for calling reshape using a 
variable for the argument. The
reshape function requires that the length of x equal the product
of the di values.
Note that arrays are stored in column format, 
which means that elements in x are transferred to the new array
y starting with the first column first element, then proceeding to 
the last element of the first column, then the first element of the
second column, etc.
