Upload signal data (amplitude data, and time in millisecond) to Signal Analyser app

I have data which are two vectors; time in milliseconds (1,2,3,4,5, etc) and Data (212,412,315, etc).

I am want to use the signal app analyzer to analyse these signals (data), but it seems to be that this app is only accepting timeseries or timeobject as inputs.

I tried to convert my data to correct format but it doesn't accept it in case of time series.

I can get it to work with a (Nx2) matrix with the time values in the first column and the signal values in the second column. (I am using R2019a.) They are not datetime, durtation, or timetable objects, simply double-precision vectors.

What data are you using with it?

I was using R2018b, but now when i switched to 2019 it worked. Thanks!

In the upper right corner of the Signal Analyzer App, there is a small round radio button with a question mark in the middle of it. Click on that to access the Help for the App.

This is also available online, with Select Signals to Analyze (link) tellilng you that you must have the signal you want to use currently loaded into your workspace. It then tells you to copy that signal from the Workspace Browser to the Filter Signals window just above it. You can then use the App to analyze the signals that are in the Filter Signals window.

Note that it is best to create a copy (right-click on the signal, then choose Duplicate option in the drop-down menu) of the signal you want to use, and then use the copy. (You can delete the copy and create other copies.) The reason is that the App will overwrite your original signal with the results of the filtering operations on it, so create a copy first to use with whatever operations you want.
