How to remove some certain rows in Matlab?

Matrix A is as follows:

    A = [45,1,1,1,2;74,1,2,3,1;75,1,1,3,1;73,1,1,1,1;53,1,1,3,2;98,1,1,1,1];

I want to find those rows in matrix A that only has array "1" and remove them from matrix A (produce new matrix C without those rows) and store them in the matrix B.

B = [45,1,1,1,2;74,1,2,3,1;75,1,1,3,1;53,1,1,3,2];

C = [73,1,1,1,1;98,1,1,1,1]

Do you mean columns? Because no row in A has only ones?

jgg, column 2 to column 5. Remove the row if there is only array "1" in for all specified columns in on a row.

Simple logical operations are all that is required:

>> idx = all(1==A(:,2:end),2);
>> B = A(~idx,:)
B =
    45     1     1     1     2
    74     1     2     3     1
    75     1     1     3     1
    53     1     1     3     2
>> C = A(idx,:)
C =
    73     1     1     1     1
    98     1     1     1     1

Ah, I think I understand: the first column are IDs or something. This should work, using the ismember function with the rows option:

 data = A(:,2:end);
 ind = ismember(data,ones(1,size(data,2)),'rows');
 C = A(ind,:);
 B = A(~ind,:);
