how can I insert text into colum?

Hi I have a FIR array 33x 13 and I want to insert on the first colum the "text" of the deFIR Vector 33x1,

FIR = zeros(33,13)
    Cimo = (0:12)
    FIR (1,:)= Cimo
    
     deFIR = {'Drive','20HZ','25Hz','31Hz','39Hz','50Hz','63Hz','79Hz','99Hz','125Hz','157Hz','198Hz','250Hz','315Hz','297Hz','500Hz','630Hz','794Hz','1000Hz','1260Hz','1587Hz','2000Hz','2520Hz','3175Hz','4000Hz','5040Hz','6350Hz','800Hz','10079Hz','12699Hz','16000Hz','20000Hz','Delay'}'

how can I insert one of the colums of my array with simple text as described!

You cannot. Your FIR array is numeric, and numeric arrays can never store text.

You can use a table, such as

FIR = zeros(33,13);  %not really
Cimo = (0:12);       %not really
deFIR = {'Drive','20HZ','25Hz','31Hz','39Hz','50Hz','63Hz','79Hz','99Hz','125Hz','157Hz','198Hz','250Hz','315Hz','297Hz','500Hz','630Hz','794Hz','1000Hz','1260Hz','1587Hz','2000Hz','2520Hz','3175Hz','4000Hz','5040Hz','6350Hz','800Hz','10079Hz','12699Hz','16000Hz','20000Hz','Delay'}';
     
t = cell2table(deFIR(2:end));
t = [t, num2cell(FIR(2:end,2:end))];
t.Properties.VariableNames = [deFIR{1},"V"+Cimo(2:end)];

t

t = 32x13 table
