Hello, Can you please look at the below screenshot and help me in simulating my file,
I have specified all parameters like B, C in the workspace and w(omega) and phi(phase difference) values by double-clicking on the blocks itself but the problem is with D2 parameter has a value varying with time. the code I wrote for D2 variation is also attached below but I need help in attaching these values with simulation file

you can use "from workspace", the D2 is a n*2 matrix, the first column is time, second row is D2 values; that how many rows depends on the time step. For example:
D2=[1 1
2 1
3 1
4 1
5 1.5
6 2
7 2
8 2
9 2];

I want the time to be the simulation time. As you can see in the .m file there is a variable called tout in 5th line which is supposed to be the simulation running time and also from your method of defining vector of n*2 I am giving discrete values for D2 (i.e at time instants of 1,2,3...10) but I want it to be a continuous variable

Try Matlab Function block in Simulink/User-Defined Functions.
You can write your code for generating D2 in Matlab Function block. The input is the Clock block from Simulink/Sources. The output is D2.
Hope it helps.
