hello Nadia
if you use readvars, you have to know / specify how many variables you want to output
example , if I specify only 2 variables in the output : (I saved your data in a txt file )
[Var1,Var2] = readvars('test2.txt')
will give me
Var1 = 4×1 cell array
{'n'}
{'n'}
{'n'}
{'n'}
Var2 = 4×1 cell array
{'1 mse_avg'}
{'2 mse_avg'}
{'3 mse_avg'}
{'4 mse_avg'}
Another alternative to get the entire data as table
opts = detectImportOptions('test2.txt');
data = preview('test2.txt',opts)
but I wonder if the way the data has been splitted ( delimiter = : ) is the way you wanted it ?
data =
4×10 table
Var1 Var2 Var3 Var4 Var5 Var6 Var7 Var8 Var9 Var10
