I have a 2D-array of positions imported from workspace. I want to increment the count to access the next element from array once a robot has reached this position. But I am unable to do so on simulink as the data that is imported is a timeseries and it continuously changes as simulation is progressing. Any help would be appreciated.

Thank you.

Have you tried the Selector block ?

One of its configurations is that the selection index can be passed in via an input port. To do this, you change the Index Option (for the dimension you want) to Index vector (port) . This way, you can increment your counter outside and change the index as you need to.

Thank you! I used index vector port to select data from a matrix. Secondly I also imported the matrix not as a timeseries but by putting the name of the matrix in constant block. This solved my problem.
