error in matrix indexing

train: matrix of 569 row and 32 column

x:matrix of 569 row of zeros &

y:matrix of 569 row of ones

now, what exactly this command did?

w=train(x,:)
w=train(y,:)

Note, this will give an error that indicate the subscript should be logical or postive

but in general

does the command w=train(x,:) calculate the size of x and then return the row of the resulted size?

You have a problem because you named your matrix train the same as the command you hope to invoke http://www.mathworks.com/help/nnet/ref/train.html .
