Hi, LabVIEW users. I'm having trouble figuring out how to wire-up the Build Waveform VI to a Matlab Script Node. My goal is to do the following:
Step 1: Use the Multitone Generator to build a Signal Step 2: Use a Get Waveform Components VI to parse the different elements of the waveform Step 3: Use a Build Waveform VI to put the elements back together Step 4: Use the Spectral Measurements VI to plot the PSD All that works..... Next, I'm trying a little experiment that will use that Matlab Node to do the FFT. I'm doing it this way because I wanted to practice interfacing Matlab and LabVIEW (both of which I'm still a rookie). Anyway, I have my input and output variables on my Matlab Script defined. The data types for the input and output variables need to be changed. When I tried the help function on the Build Waveform VI, I came across a symbol for a datatype I haven't seen- its the one for the t0 variable on the Build Waveform VI. I tried changing my input data type for the Matlab Script, but the ones I've tried (real, real vector, script) seem to break the entire wire between the Get Waveform Components and the Build Waveform Components VI, respectively. Suggestions? Gary Thomas, Work: 1-703-377-1500
