feijoa,
I am not too familiar with how you can use the matrix data in Matlab, but I can show you how to organize the data points into a matrix in LabVIEW. I can also show you how to store this data to a file if that is what you really want to do. We can start with the matrix and go from there.
To use the matrix, you can wire a 2D array of numerics to the matrix indicator. Depending on how you acquire your data points, this will most likely require 2 loops. In the inner loop, you can build a 1D array that corresponds to the first waveform. When this loop completes writing the 10,000 points to an array, you can then wire the output to the wall of the outer for loop and enable indexing. Thus when the outer loop executes 10 times, the output from the indexed terminal will be a 2D array with each column representing data points for one waveform. I have attached a small example that should demonstrate this concept. I hope this helps! Please let me know if I can help further. Thanks,
