Lets say I have an array of bearing angles such as: [0, 90, 0] and I want to use elements a that are equal to zero. I then want to use the data in another array of displacments [10, 10, 20], that are in the same positions as the angles that meet the condition in the first array. Im not sure how to do this, I figured out how to use the displacment and angle to then find x and y coordinates Im just not sure how to do this.

Read about logical indexing: https://www.mathworks.com/company/newsletters/articles/matrix-indexing-in-matlab.html
a = [0, 90, 0];
b = [10, 10, 20];
y = b(a==0)
Result
>> y
y =
10 20
