**Hi
I can extract through and across variable data from Simscape but i want the parameter data in Matlab workspace as well. I do not know how to do that. For example : In the code below, my parameter is L1, L2 and I want them in the workspace as well for plotting.
Could anyone can help me?**
component mutual_inductor
% Mutual Inductor :2.0
% Models a mutual inductor. If winding 1 has voltage V1 across it and
% current I1 flowing into its + terminal, and winding 2 has voltage V2
% across it and current I2 flowing into its + terminal, then
%
% V1 = L1*dI1/dt + M*dI2/dt
%
% V2 = L2*dI2/dt + M*dI1/dt
%
% where parameters L1 and L2 are the winding self-inductances, and
% M is the mutual inductance. M is defined in terms of major radius, minor
% radius and number of poloidal turns with the equation
%
%M_Lt = meu_0*N_t*a^2/(2*R); M_pL = 0.2*M_Lt;
%M = N_t*M_pL
%So finally, M = 0.2*meu_o*(N_t^2/(2*R))
%
% The parameters Winding 1 initial current and Winding 2 initial current
% set the initial current through windings 1 and 2. Note that this value is
% not used if the solver configuration is set to Start simulation from
% steady state.

v2 == L2*i2.der + ((meu_0*0.2*N_t^2*a^2)/(2*R))*i1.der;
end

If you plot a variable from you SimScape model, you have to put a sensor that measure what you want. If you want to get the voltages, you have an option:
Once you have your "Physical Signal", transfor to Simulink signal using the Block Parameter: "PS-Simulink Converter".And Finally, put at the end a scope, that will give your data.
For get the values from your ScopeData, you have to enter to the parameter on the scope and in the tab of "History" choose "Save data to workspace" and then name your variable.
At the end in your script you have to write something like this (an example):
model = 'Name of your simulink program'; sim(model); time = ScopeData(:,1); X1 = ScopeData(:,2);
