MATLAB: Operands on table, comparison with numbers

MATLABoperandstabletable2array

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)
ans = 8x4 table
      LastName        Gender      Age    Smoker
    ____________    __________    ___    ______

    {'Smith'   }    {'Male'  }    38     true  
    {'Johnson' }    {'Male'  }    43     false 
    {'Williams'}    {'Female'}    38     false 
    {'Jones'   }    {'Female'}    40     false 
    {'Brown'   }    {'Female'}    49     false 
    {'Davis'   }    {'Female'}    46     false 
    {'Miller'  }    {'Female'}    33     true  
    {'Wilson'  }    {'Male'  }    40     false
But if you can, you can use curly braces to extract the data into a numeric array.
A = magic(4)
A = 4×4
    16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1

T2 = array2table(A)
T2 = 4x4 table
    A1    A2    A3    A4
    __    __    __    __

    16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1

T2{3, :} % The same as A(3, :)
ans = 1×4
     9     7     6    12
