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.?

Thanks and Regards,

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

[rahut patil]

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,

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,

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,

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