Importing time-varying variables from Matlab to Simulink

Hi there,
I'm trying to use several variables in a simulink design which are initially calculated iteratively in a Matlab script, like this...
for k=2:1:N(2) % Solve for Lambda and Gamma
funL =@(w) samplingT*(Km(:,:,k) - (Cm(:,:,k) - Lambda(:,:,k-1)) * Lambda(:,:,k-1)) + Lambda(:,:,k-1) - w;
Lambda(:,:,k) = fsolve(funL, eye(2));
Gamma(:,:,k) = Cm(:,:,k) - Lambda(:,:,k);
end
My problem is how to set up the "to workspace" structure, in terms of time, values and dimensions (Gamma and Lambda are 2x2 matrices for example).
Any help would be appreciated.
Regards, Alex

If you have 2 dimensional data you could use a 2-d lookup table.

If the input is based on time you can utilize a clock or digital clock as one of the inputs to utilize time.
