Hi .I have a table after reading a csv file with readtable .I attached a sample file .Say I get a table A after reading.
say I fix one of the row indices " ind" .If I try say find(A(ind,:)>0.1) I get the error : "Operation '>' not supported for operands of type table " .In general how do I just go back to some classic matrix from a table ignoring these Variable names?
I tried table2array but with no luck .Many thanks

There's no guarantee you can "slice" the table across rows -- the variables may contain data of different data types.
load patients
T = table(LastName, Gender, Age, Smoker);
head(T)
But if you can, you can use curly braces to extract the data into a numeric array.
A = magic(4)
T2 = array2table(A)
T2{3, :} % The same as A(3, :)

You have to access the columns of Table T using T.(1), T.(2) etc,
Read about accessing the columns from tatble. If you have names to the columns, you can use
T.col1, T.col2 etc to access the respective columns.
