Hi, I am trying to read an nx1 matrix from my workspace into my Simulink model one at a time. Ideally, I'd like to be able to use the discrete Delay blocks and view the outputs side by side with the non-delayed signal. Suppose my matrix is a column that counts from 1 to 10. I'd like to import that matrix in such a way that if I hooked up a scope, the scope would output something that looked like a step counter from 1 to 10 which stepped up once per sample time.
To try to be more clear: I have a matrix that contains data points. Each data point was captured at a fixed rate after the previous sample. This could be an example of my matrix:
1
2
3
4
5
6
7
8
9
10
So I'd like to view that in a scope in Simulink as I described above. If those were my data points, I would want the scope to cycle through each entry in the matrix as the simulation progresses. My actual data points will be doubles that are not evenly incrementing like that, they are data points captured from a sinusoidal type wave. Additionally, I'd like to run a wire from that matrix into some discrete delay blocks so that I could compare the value of the matrix during the present sample to some delayed sample. So, if I have a discrete delay block set to delay the signal by 2 samples, I could compare my signal in its current sample to what it was 2 samples ago, so that if I hooked both current and delayed signals up to a scope I could view the data side by side. I do know the actual sample start time and increment time, so if I have to create a new matrix combining the data with a time stamp that would be a possibility, but I would like to avoid that if possible.
I have tried using constant blocks, but they just display the entire matrix all at once. Some other data import blocks require a separate time column, which I would like to avoid since my system doesn't rely on time in any other way due to the constancy of the timing. I am just looking for a way to import my matrix in such a way that each row can be considered a sample.
I hope this has been a clear enough explanation. I already have an enormous model built that will entirely rely on being able to read in data in the way that I have described, so I would like to have my data import method fit the parameters I have described. I realize I should have figured this out first, but that's just how it goes I suppose. Thanks in advance for any help or guidance.
