mlist

Scilab Function
Last update : 25/04/2007

mlist - Scilab object, matrix oriented typed list definition.

### Calling Sequence

  `mlist(typ,a1,....an )`

### Parameters

- `typ` : vector of character strings
- `ai` : any Scilab object (`matrix, list,string...` ).

### Description

mlist object are very similar to tlist objects. But if `M` is an mlist, for any index `i` which is not a field name, `M(i)` is not the `i` th field of the list but is interpreted as the `i` th entry of `M` seen as a vector. This is the only difference between `mlist` and `tlist` .

mlist fields must then be designed by their names. They can also be handled using the `getfield` and `setfield` functions.

### Examples

    M=mlist(['V','name','value'],['a','b','c'],[1 2 3]);
    //define display
    deff('%V_p(M)','disp(M.name+'':''+string(M.value))')
    //define extraction operation
    deff('r=%V_e(i,M)',..
    'r=mlist([''V'',''name'',''value''],M.name(i),M.value(i))')
    M(2) // the second entry of the vector M
    M.value

    //define M as a tlist
    M=tlist(['V','name','value'],['a','b','c'],[1 2 3]);
    M(2)

    M('name')

    //with two  indices
    M=mlist(['V','name','value'],['a','b';'c' 'd'],[1 2;3 4]);
    deff('r=%V_e(varargin)',[
        'M=varargin($)';
        'H=[''V'',''name'',''value'']'
        'r=mlist(H,M.name(varargin(1:$-1)),M.value(varargin(1:$-1)))'])

    M(:,2)
    // multidimensionnal array
    str=['a','b','c','d','e','f','g','h'];
    n=hypermat([2,2,2],str);
    v=hypermat([2,2,2],1:8);
    M=mlist(['V','name','value'],n,v);
    M(1,1:2,2)
