Simulink vector to bit a second

I have a vector [1, 1023]. To exampe: [1, 0, 1 ... 0], but I want to send only one bit a second from vector in simulink. How I can do that? I want to pass the number to another block and so on 1023 times.

[Fangjun Jiang]

You mean a vector like [1, 0, 1 ... 0], every value is either 0 or 1, the total length is 1023?

[Anton Naymov]

Yes. Function returns a vector.

I use matlab function block to generate vector, but I need to work with every bit from a vector(by one).

If you want to feed a vector like [1, 0, 1 ... 0], in which every value is either 0 or 1, the total length is 1023, at a rate of one value per second, then first form the data

data=[1,0,1, 0,1,0,0];
time=[0:numel(data)-1];

Then use the FromWorkspace block and specify the data as [time(:), data(:)].

This will feed the data as desired.

If your data is generated by a MATLAB Function block, you need to keep in mind that the MATLAB Function block is executed at every simulation step. Is the 1023-value data generated at once during one simulation step, or is the data generated one-value-at-a-time?

If the data is generated at once, it is better to generate the data separately and use the FormWorkspace block to import the data.

If the data is generated one-value-at-a-time, then your question is moot.

[Walter Roberson]

If the vector is generated all at once, you can use a DSP block to buffer it from the original size to one sample per frame. However, that has the effect of speeding up the sample rate, as Simulink expects that at the next time it runs the vector production block that there will be a full vector available again.
