Hi. I need to change all lines with 101 and [100;101] in 'test_2' with '[]' in both 'test_2' and 'test_1'.

I succeeded with 101, but can't get the same result with [100;101].

'test_1_out' and 'test_2_out' are the results I need to obtain.

test_1 = importdata("test_1.mat");
test_2 = importdata("test_2.mat");
for K = 1:length(test_1)
    if test_2{K,1} == 101
        test_1{K,1} = [];
        test_2{K,1} = [];
    
    end
    
    if test_2{K,1} == [100;101]  % error
        test_1{K,1} = [];
        test_2{K,1} = [];
    end
end

        test_1(K, 1) = [];
        test_2(K, 1) = [];

Hii Alberto Arci,

I understand you want to debug the code and get the desired output.

Solution given below might be one of the possible workflow:-

test_1 = importdata("test_1.mat");
test_2 = importdata("test_2.mat");
for K = 1:length(test_1)
    if isequal(test_2{K,1}, 101) || isequal(test_2{K,1}, [100;101])
        test_1{K,1} = [];
        test_2{K,1} = [];
    end
end
