Convert N-dimensional cells of K-dimensional matrices to N*K matrices.

File Information
Description

Neither previous CELL2NUM or CELL2MAT can deal with cells and matrices of arbitrary dimensions. Hence my submission.

This function convert a multidimensional cell INPUT composed of multidimensional matrices to a matrix OUTPUT. The only requirement is that all the matrices have the same dimensions.

Given N = size(INPUT) and K = size(INPUT{1}) the size of OUTPUT will be [N x K].

Example 1:
N => [2 3]
K => [4 3]
OUTPUT => [2 3 4 3]

Moreover it is possible to set parameters in order to eliminate eventual singleton dimensions or convert either N or K to equivalent vectors.

Example 2:
N => [1 3]
K => [4 1 2]
OUTPUT => [3 4 2]

Example 3:
(changing parameters)
N => [2 3]
K => [4 3]
OUTPUT => [6 4 3]

Example 4:
(using parameters)
N => [2 3]
K => [4 3]
OUTPUT => [2 3 12]

Example 5:
(using parameters)
N => [2 3]
K => [4 3]
OUTPUT => [6 12]

Yes, you are correct, the examples in the description are abstract. However "Demo_cell2num" contain numerous real examples as well as many combinations of the possible parameters that you can use.
I'll try to change the description to explain it better.

The examples in the description are abstract. An explicit code would be more useful than the need to guess, what "(using parameters)" is or what "OUTPUT => [2 3 12]" could mean.
Please improve these details.
