I am not too sure on how to write a function that takes in as inputs a string containing the name of a directory that the images are contained in, and a 1xn 1D array containing n strings where each element is a filename of an image to read.
the function needs to return one output; a 1D array containing n images where each element is an RGB image.
Any help would be appreciated:)

D = "path of the directory where the images are saved";
S = ["string array","of","the image filenames"];
N = numel(S);
C = cell(1,N);
for k = 1:N
F = fullfile(D,S(k));
C{k} = imread(F);
end

What I posted is a function already. The only thing it is missing is returning the images as a 1d array.

Datastores are convenient for reading collections of files.
imds = imageDatastore(directory)
imshow(read(imds))
Each time you call read, it will give the next image in the directory.
