Aligning the Inputs and Outputs through m script

Please see this link : http://i50.tinypic.com/vsdool.jpg

I am trying to create the input and output port automatically(thru m script). I am taking the Subsystem portHandles.Inport position and setting the postion for input. Once all the input and output are created, it is mixed with one and other. Please see the link for the screen shot. The signal names are not clearly visible to read. Is there any way to leave the gap between the two input(or output) ports?

try this to understand how to do it

 % model1 : your model  Name
 % sub1: your  subsystem name
tailx=50;taily=25;
x0=50;y0=50;yy0=y0;
for k=1:n
    x=x0+tailx ;y=y0+taily
    inp=['model1/input' num2str(k)]
    add_block('Simulink/Sources/In1',inp)
    set_param(inp,'Position',[x0 y0 x y ])
    add_line('model1',['input' num2str(k) '/1'],['sub1/'  num2str(k)],'autorouting','on' )
    y0=y+20
end

what is yy0 =y0? yy0 is not used any where in the loop.

[Azzi Abdelmalek]

because y0 is changing, yy0 will be used to set position of the output

Thank you Azzi

Imagine a chart over layed on the subsystem. Draw where your margin lines are.

xspacing = [inportL inportR     outportL outportR]; 
     %column margins (left/right of blocks)
ystart = 100; % however far down you start
yhalf = 10; % block half width
dy = 30; % height of the row

for ii = 1:insigs
    blockname = insig{ii};
    addblock(...)
    setparam(blockname_handle,'Position',[xspacing(1) ystart+ii*dy+yhalf xspacing(2) ystart+ii*dy-yhalf]);
end

for ii = 1:outsigs
    blockname = outsig{ii};
    addblock(...)
    setparam(blockname_handle,'Position',[xspacing(3) ystart+ii*dy+yhalf xspacing(4) ystart+ii*dy-yhalf]);
end

something like that

[Moorthy]

will u plz explain the 'xspacing' initialization? xspacing = [inportL inportR outportL outportR];

[Albert Yam]

Think of a box, [], top left corner is x1,y1, bottom right is x2,y2. set_param 'Position' needs x1,y1,x2,y2

inportL = x1 of your inports, the vertical line that you want to align the left of all your inports to.

inportR = x2 of your inports, the vertical line that you want to align the right of all your inports to.

Now when looping inports, x1 and x2 do not change. But y1,y2 does, by ii*dy each iteration, and y1 and y2 are separated by 2*yhalf.

similar for outports

Thank you Albert.
