Hello all,
I want to define the array in simulink which consist of 'n' elements in it.
Can I read and write the array elements individually? If yes. How.?
please tell me as early as possible.
Thanks and Regards,
Rahut Patil.

Use constant block, what do you mean by read and write the array individually?

how can I use the conststant block?
Write : I will write the values of array elements in running mode.
read :I will read the values of array elements in running mode.
Thanks and Regards,
Rahut Patil.

Hello Madhan,
I tried but it is giving the following error when I import the vector from workspace. I tried by changing the data types and sample time -1 to 0 and vice versa. But it is giving same error.
=== Simulation (Elapsed: 0.325 sec) ===
Error:Unsupported input format for From Workspace block 'Array/From Workspace'. Available formats are double non-complex matrix, a structure with or without time, or a structure with MATLAB timeseries as leaf nodes. All formats require the data to be finite (not Inf or NaN).
Thanks Regards,
Rahut Patil.

Hi Madhan,
I got the solution. I need to run the array in the command window. But want to assign a value to the perticular array element in the running mode. Can it be possible in simulink? Please suggest.
Thanks Regards,
Rahut Patil.

% MATLAB Function code
function y = fcn(u,index_number,value_assigned)
y = u;
y(index_number) = value_assigned;
