call with matlabfunction(simulink) an other mfile

Hi, i have a simulink model, which computes a value, then i give this value to a matlab funktion, then fron this matlab funktion i wanna call an other mfile funktion and give this mfile function this value.

How can i call an other funktion and give a value???? THX

Look at Matlab function or Interpreted matlab function

[sia]

yes i did. maybe i should say more: The matlabfunction in simulink calls a mfile function, which is not in simulink, and this has already 4 inputs.

The matlabfunction in simulink is like that:

      function y = load_handles(u) 
     %#codegen

   y = test_environment(u);
      end

and the head of the other function is that

    function y = test_environment(i,d,c,alpha)

how can i add u into that????

[Azzi Abdelmalek]

function y = load_handles(i,d,c,alpha) 
   %#codegen
 y = test_environment(i,d,c,alpha);

[sia]

that is not right :(... because

   load_handles(u)

get only one input "u"

I want only call this function:

   function  test_environment(i,d,c,alpha)

and put "u" into this.

[Azzi Abdelmalek]

And what are i,d,c,alpha ? constants or signals?

[Azzi Abdelmalek]

If they are constants, you can use Ports and Data Manager

[sia]

actuelly the function looks like this :

     function  test_environment(i,d,c,alpha)
     switch(nargin),
     case 0
     i = [5 5 5];
     d= [1 1 1];
      c= 'b';
      alpha = 0.5;
   case 1 ....

now i want call this function from matlabcunction in simulink and give the input "u" additionally.

[Azzi Abdelmalek]

You did not answer my question, what are i,d ,c and alpha constants or signals? how are they used in your simulink model?

[sia]

they are constants for building a geimetry. i = [x y z] d = [dx dy dz] voxlesize c = color

I added my function into the matlabfunction, looks like this

    function y  = handle (u)
    y = test_environment(u);
    function  y = test_environment(u)
    switch(nargin),
     case 0
   i = [5 5 5];
   d= [1 1 1];
   c= 'b';
   alpha = 0.5;
   case 1
    l=1;    %default length of side of voxel is 1
    c='b';  %default color of voxel is blue
     case 2,
    c='b';
     case 3,
    alpha=1;
    case 4,
    %do nothing
     otherwise
    disp('Too many arguements for voxel');
   end;
   x=[i(1)+[0 0 0 0 d(1) d(1) d(1) d(1)]; ...
        i(2)+[0 0 d(2) d(2) 0 0 d(2) d(2)]; ...
        i(3)+[0 d(3) 0 d(3) 0 d(3) 0 d(3)]]';
   for n=1:3,
    if n==3,
        x=sortrows(x,[n,1]);
    else
        x=sortrows(x,[n n+1]);
    end;
    temp=x(3,:);
    x(3,:)=x(4,:);
    x(4,:)=temp;
    h=patch(x(1:4,1),x(1:4,2),x(1:4,3),c);
    set(h,'FaceAlpha',alpha);
    temp=x(7,:);
    x(7,:)=x(8,:);
    x(8,:)=temp;
    h=patch(x(5:8,1),x(5:8,2),x(5:8,3),c);
    set(h,'FaceAlpha',alpha);
    %WeltkoordinatenSystem
    axis([0,10,0,10,0,10])
    xlabel('X-Achse')
    ylabel('Y-Achse')
    zlabel('Z-Achse')
    grid on
    hold off
  end;
  end

You do not need to put the m-file in your Matlab fcn block, you have just to call the function in the block Matlab fcn. but you need to use i,d,c,alpha as constants or signals

function y = load_handles(i,d,c,alpha) 
 %#codegen 
y = test_environment(i,d,c,alpha)
