Hi,
I have an 1-D array (ex: A) with a size exactly matching that of the total simulation steps. This array can be either stored in model or base workspace.
I need to set a block parameter to A(Index) with its index changing according to the simulation time.
How can I do this?
Thank you for your help.

Use a Selector block. Choose the 'Index option' as 'Index vector - port'. Then connect A to the U port and feed the Indx1 port with an integer that you develop from the the simulation time.

If implemented properly, the output of the selector block is A(index). Multiply it with the output of a Clock and then input the product into a Trigonometric Function block.
Another way to get A(index) is to use the 1-D Lookup Table block. Specify 'Flat' as the interpolation method. This approach would probably be easier than using the Selector block.

Thank you.. I used set_param to update A(Index) in my block.
