Will the following code work to generate a random integer between 0 and 180?
length = 180;
random_location = randi([0 length], 1);

Don't use length as a variable name because it's the name of a built-in function. Try it this way:
% Generate a single integer, randomly chosen from the range 0 to 180, inclusive.
maxValue = 180; % Not using length because it's a built-in function.
randomInteger = randi([0, maxValue], 1, 1) % Generate the column vector.

Yes.
length = 180;
random_location = randi([0 length],1E6,1);
[min(random_location) max(random_location)]
histogram(random_location,'binmethod','integers')

That's the height of the array; i'm specifying that I want a 1000000x1 column vector from randi(). The reason I chose to get a large vector instead of 1 number is so that I had enough samples to demonstrate (via histogram) that the results are uniformly distributed between the specified limits. You can specify whatever output size you need.
