the output matrices i'm getting are of sizes t1=23*1, f1=33*1 and tf1=33*23. My question is how t1,f1 matrices sizes are determined i.e, what is the formula used to get the sizes of matrices based on window length and overlap. Here my signal size is 720*1, window length is ...

fft Transform time-domain data to the frequency domain. You can specifyN, the number of frequency values. To transform time-domainiddataobjectt_datato frequency-domainiddataobjectf_datawithNfrequency points, use: f_data = fft(t_data,N) ...
For example, in the context of large manufacturing plants, the anomaly detection on their products based on sensors producing high data volume, requires a compromise between high accuracy and low latency. Therefore, the complete pipeline should be designed with a mindset of being able to run the...
How do I use a CSV file to do a FFT? I Can do a FFT using excel. However, I keep hitting walls with matlab. The goal is to us the fft to find component frequencies in order to attempt to reconstruct the recorded sound with the appropriate sin/cos wave functions. ...
