file io - Matlab Importdata -

-

i'm writing piece of code supposed import text files using importdata , count number of columns, thought cols() function suffice this, seems imported data stored double, meaning can't perform operation.

m=importdata('title'); numcols=cols(m.data);

am doing wrong? thought data fromthe text file stored in matrix/array?

cols specific function use in database toolbox.

you want use size function. eg:

size(m.data,2);   %returns number of columns

fyi

size(m.data, 1); %returns number of rows.
