I am trying to find the index of a value in an array which I used an equation to determine and saved as a variable. This is what I would like to happen, but I get an error:
azimuth_angle = 180 + atand(b/a); % The equation yields an azimuth_angle of 195, which is a value in the array azimuth_z.
azimuth_index = find(azimuth_z == azimuth_angle); % azimuth_index should give me 337, which is the index I want, but it only works when I replace azimuth_angle with the value it is (195).
Where azimuth_z is a 360x1 single and b and a are just values.
Is there a way to use find() with a variable? Or is there another function I need to use?
