```
function I = ImageFrom3DVector(v)
```

%% ImageFrom3DVector(v) Displays an image whose RGB-values are determined by the coordinates of v % This is an example of a "loop", % which creates a stack of three matrices % containing integers that MATLAB can use % as RGB pixel values in an image for i = 1:3 % execute the line below 3 times I(:,:,i) = uint8(repmat(v(i),600,900)); % repeat the number stored in v(i) across a 600x900 matrix end % every loop statement needs an "end" % Display the image stored in I imshow(I);
