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

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????

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

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.

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

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.

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

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)
