Simple simulink problem

Ashwini Deshpande — Wed, 21 Oct 2009 06:19:02 -0400

Hi,

In simulink i have defined a array as follows using constant block:
a=[1 0 1 1 1 0 0 0 1];

Now i want to read the elements of array 'a' one by one, i mean at every sample time one element in ascending or descending order.

How do i do this ??

In otherwords if scope block is connected to the arrary, i suppose to see a binary signal of zeros and ones there.

Thanks !
Ashwini

Don't use the constant block, use the repeating sequence block:

Thanks ,
My requirement something similar to the repeating sequence block, there i want to have the sequence of zeros and ones, but it expects that the sequence should be in ascending order.
what do i do??

You are right, I was a bit too hasty. Use the repeating sequence stair block
instead:
