Undefined function 'train' for input arguments of type 'struct'

This is my problem:

Undefined function 'train' for input arguments of type 'struct'

I have The code:

    Input =  xlsread('Variabless',4);
    Target = xlsread('Variabless',5);
    Sample = xlsread('Variabless',6);

Variabless is a matrix on excel with a lots of data, but each of this data is a formula not a number.example: =Hoja3!A6

Can matlab reads numbers and string only??

How can I read =Hoja3!A6 on matlab and play like a number.?

Thanks.
