MATLAB: How to remove some certain rows in Matlab

arraycell arraysfunctionmatrix manipulationunique

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]

Best Answer

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
