csv - Matlab csvread() creating wrong matrix -

-

i want import matrix .csv matlab , find matlab acting differently wrt length of row in csv. :

first, read file of 2 rows 50000 columns , matlab correctly shows 2*50000 matrix in workspace. now, if file consists of 2 rows 100000 columns, matlab identifies 200000*1 matrix.

what has gone wrong there?

what command using? csvread('filename.csv') ?

i prefer use

data = importdata( 'filename.csv','\t');
