Im getting this error when i run my code
This is the code i am running
data = readmatrix('project.xlsx')
Tbl = array2table(data);
varNames = ["Number","Amplitude","PSD","Recurrence_Rate","Recurrance_Points","Determinism","Ratio_Determinism_Recurrence_Rate","Average_Diagonal_Length","Average_Vertical_Length","Laminarity","Divergence","Entropy","Trapping_Time","OSA_Label"];
mdl = fitcdiscr(Tbl, Number)
Please help troubleshoot this

I believe you meant this:
mdl = fitcdiscr(Tbl, "Number")
instead of
mdl = fitcdiscr(Tbl, Number)
Edit: Also what does your table look like? Does it have those variable names?

What does your table look like in MATLAB? Does a column have all NaN values?
Edit: Also, if your spreadsheet has the variable names in them, you could just use the readtable function.
What happens if you remove those columns?
data = rand(8,3);
Tbl = array2table(data)
You can remove a column programmatically as such:
Tbl.data2 = []
FYI, you could use the import tool to import your data and then generate a function to import similar data files in the future. See link below.

Is it possible that you can share your Excel sheet or one with similar data?
