cell

creates a cell array of empty matrices

Calling Sequence

```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).entries`. The expression `A(1,1) = zeros(2,2)` is not valid, the right syntax is `A(1,1).entries = zeros(2,2)`.

If `A` is a cell array, you can get its dimensions by using `A.dims` which returns an `int32` value that cannot be used as a subscript for the cell array. In this case, the best way to get the cell array dimensions is `size(A)`.

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 the 'entries' field
b(1).entries=1:3

// Assigning the second element of b using the 'entries' field
b(2).entries='Scilab'

// Assigning the third element of b using the 'entries' field
b(3).entries=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).entries

// Dimensions of b as an int32 value (cannot be used as an index)
b.dims
// Dimensions of b as a double value
size(b)```
