Apply condition to specific column and extract data from that row

Hi, I'm working with a matrix with 3 column and n amount of rows

I want to apply a condition to the 1st and 2nd column, then extract the data from the 3rd column which the condition is matched.

for example, I have A =

1 2 3

2 6 6

1 8 5

3 2 7

8 4 3

6 8 1

I want to extract the data from 3rd cloumn in the row where the condition are,

• value of the 1st column in less that 5
• value of the 2nd column is more that 5,

Therefore, I will have data from 2nd and 3rd row (6 and 5)

A = [1 2 3

2 6 6

1 8 5

3 2 7

8 4 3

6 8 1];

idx_row = (A(:,1) < 5) & (A(:,2) > 5);

A(idx_row,:)
