Signal Labeler is not loading the data

Hello,

I am using MATLAB 2020a, I have a matrix of signals that I want to label using signalLabeler. The matrix is in my workspace but signalLabeler is not recognizing it and thus it is not imported.

Any help is appreicated.

[Mehmed Saad]

what is the dimension of you matrix

[Khaleel Alhalaseh]

2631x75

[Khaleel Alhalaseh]

even if I only took 500x75 it still does not show

they need extensive documentation for that

[Mehmed Saad]

create a random varaible of same size and try labeling it.

z = randn(2631,75);

Type of data? double,uint ?

[Khaleel Alhalaseh]

Double

[Khaleel Alhalaseh]

I created a random matrix and it was able to import it.

[Mehmed Saad]

then your data might have some problem

[Khaleel Alhalaseh]

I checked my data it has InF and NaN. Gotta find a way to handle that. any suggestions?

Answer 1

[Mehmed Saad]

Now Try this

z = randn(2631,75)+1j*randn(2631,75);

You cant see z in signal analyzer because it is complex

I beleive your data is complex double

zr = real(z);
zi = imag(z);

Now you can see zr and zi in signal Analyzer

[Khaleel Alhalaseh]

No. It contained NaN and InF but I fixed them, still signalLabeler does not recognize their existence in the workspace.

can you share your data in mat file
