I have a funtion which recibe some variables, in thus funtion I'am calling a simulink block and getting some datas...
The problem is I need this Var1 Var2 in Simulink block ? What can i do ? To use this vars values in my simulink ??
function [Out] = Funtion (Var1, Var2 ....)
simout = sim('Simulinkblock');
Yx = simout.yout{1}.Values.Data;
Cx = Yx(end);

As per my understanding you want to pass the input to your Simulink Model through as an input to the function.
This issue can be resolved if you have root inport in your Simulink Model by using setExternalInput (Refer to example code for understanding).
Other approach could be loading data from Workspace, for that you can refer to From Workspace or using MAT file to provide input.
Hope this helps.

Try using a Simulink.SimulationInput object. Change the code to:
function [Out] = Funtion (Var1, Var2 ....)
in = Simulink.SimulationInput('Simulinkblock')
in = in.setVariable('D',Var1); % to set the value of D. Repeat for others as needed.
simout = sim(in);
% simout = sim('Simulinkblock');
Yx = simout.yout{1}.Values.Data;
Cx = Yx(end);
