Multiply a cell with a scalar number

Hello all, i have a problem in multiply my cell in Matlab. I have 1x5218 cell wich i want to multiply it with a scalar number. First, i used code like this,

t = readtable('100Hz.csv');
input = t.x10000(1:5218);
new_input = input.*2;

it return,

Undefined operator '.*' for input arguments of type 'cell'.

Error in FFT_Matlab (line 3)
new_input = Input.*2;

how i solve this problem ? Thank you

Please attach you .csv file

Although I can imagine you can easily fix the problem by writing

t = readtable('100Hz.csv');
input = t.x10000{1:5218};
new_input = input.*2;

But I won't be 100% sure until you share the file.
