Problem with table, error 'Unrecognized row name '...' '

This is my code:

Fluidi={'Dowcal 20';'Dowtherm Q';'Therminol XP'};

Tempo=[length(x1);length(x2);length(x3)];

T=table(Fluidi,Tempo);

disp(T)

Matlab gives me this error: Unrecognized row name 'Dowcal 20'.

Why?

Thanks to everybody will help me

Answer 1

[Walter Roberson]

You are not creating named rows in your table. Named rows have to be set by the RowNames property of the table, such as

T = table(Tempo, 'RowNames', Fluidi)

There's something you're not telling us (probably what Walter suggests):

>> Fluidi={'Dowcal 20';'Dowtherm Q';'Therminol XP'};
>> Tempo=[1;2;3];
>> T=table(Fluidi,Tempo);
>> disp(T)
        Fluidi        Tempo

    'Dowtherm Q'        2  
    'Therminol XP'      3
