How to remove the row of matrix which contains same value in specific columns?

I have a dataset (just a subset of a larger dataset, attached excel file). In the dataset, I want to remove the rows which have 1 in 3rd and 4th column. How can I do it in MATLAB.

Answer 1

[KSSV]

[num,txt,raw] = xlsread('delete_one.xls') ;
num(num(:,3)==1,:) = [] ;   % remove rows with one in thrid column
num(num(:,4)==1,:) = [] ;   % remove rows with one in fourth column

For flottant numbers better to use:

tol = 10^-3 ;
num(abs(num(:,3)-1)<tol,:) = [] ;
num(abs(num(:,4)-1)<tol,:) = [] ;
