cell creates a cell array of empty matrices

## Syntax

                c = cell()
                c = cell(m1)
                c = cell(m1, m2)
                c = cell(m1, m2, ..., mn)
                c = cell(x)

## Arguments

x

  a vector containing the dimensions of the cell to create.

m1, m2, ..., mn

  dimensions of the cell to create.

## Description

`cell` returns a cell array of empty matrices.

cell()

  returns a `(0, 0)` cell array of empty matrices.

cell(m1)

  returns a `(m1, m1)` cell array of empty matrices.

cell(m1, m2)

  returns a `(m1, m2)` cell array of empty matrices.

cell(m1,m2,..,mn)

  creates a `(m1, m2, ..., mn)` cell array of empty matrices.

cell(x)

  returns a cell array of empty matrices with: the first dimension of the cell array is `x(1)`, the second dimension is `x(2)` and so on.

## Remarks

`cell(x)` is not the same size that `x`.

`cell()` is equivalent to `cell(0)`.

If `A` is a cell array, you can access the contents of an element of `A` by using `A{m1, m2, ..., mn}`. The expression `A(1,1) = zeros(2,2)` is not valid, the right syntax is `A{1,1} = zeros(2,2)`.

## Examples

    a = cell(3)
    b = cell(3,1)
    c = cell([2,3,4])

    // Assigning cell entries
    b = cell(3,1);

    // Assigning the first element of b using {}
    b{1} = 1:3

    // Assigning the second element of b using {}
    b{2} = 'Scilab'

    // Assigning the third element of b using the 'entries' field
    b{3} = poly(1:3,'s')

    // Assigning sub-cells
    X = cell(3,2);
    X{:,1} = b

    // Extracting a sub-cell: result is a cell
    b{1}
    b{1:2}

    // Extracting a sub-cell value: result is an array
    b{1}

    // Dimensions of b as a double value
    size(b)
