"Not enough input arguments" error using add_line()

Hello !

I'm trying to use add_line() function and to organize link with the 'autorouting' parameter. Here is my code :

add_line(sprintf('%s',diagrammeName), [pos_array_out{pos_out};pos_array_in{pos_in}], 'autorouting','on');

where pos_array_out is a cell of Output position and pos_array_in is a cell of Input position.

And pos_in and pos_out are index of cell.

But it returns me an error :

Not enough input arguments

And i don't understnd why

"...i don't understnd why"

Read the error message!

According to the add_line documentation you can supply these input arguments:

add_line(sys,out,in,'autorouting',autoOption)

but in your code you have concatenated out and in into one array. Try this:

add_line(sprintf('%s',diagrammeName),...
    [pos_array_out{pos_out}],... OUT
    [pos_array_in{pos_in}],... IN
    'autorouting','on');

The problem is that pos_array_out{pos_out} is a Position from get_param('System', 'PortConnectivity') (for example 150 75) and so it returns me Invalid Simulink port handle when i do like you say

I'm using this way of {add_line()function : h = add_line(sys,points)`
