I have a project in optical communcitaion, were i want to send a laser thorugh polarised light to a photodioder, then to two DAQ:s, one will retrieve the signal and one wants to send, and that works. Now i want to transalte the one:s and zero:s do display on a screen, what the message is, the variable namne in workspace for the recorded signal is called DAQ_1, i seem to get a problem when i have the code for i = 1:lenght(DAQ_1), i get an error. What should i change in my code?

" the variable namne in workspace for the recorded signal is called DAQ_1, i seem to get a problem when i have the code for i = 1:lenght(DAQ_1), i get an error."
Please copy and paste the full error message, that means all of the red text.
"% Assume that DAQ_1 is the variable you have in the workspace with the binary sequences"
Yeah, that won't do. You will need data to run the code.
Is DAQ_1 supposed to be obtained as user input? Or is it obtained from another source?

DAQ_1-You can validate the code by inputting random 7 bits in string format using an array structure, which could occur in real-time testing as well.
