Hello everyone,
I have a set of matrix, called att_power:
I need to use a for loop to call some of the values in the first column of the matrix, such as I could be calling 5, 15, 30, and 50 only.
Based on the values, I am calling, I need matlab to create matrix showing the corresponding values in the second column.
In this case, I want to matlab to create a matrixx, showing [4.2, 32, 115, 273]
Can anyone please help me on this?
Kind regards,
Nilesh

vals = [5 15 30 50];
idx = ismember(att_power(:,1),vals);
result = att_power(idx,2)
