I am trying to perform this simple operation on CVX toolbox.
[a b; c d]-[x;y] which should be equal [a-x b-x;c-y d-y].
CVX does not support implicit expansion, which was introduced into MATLAB in R2016b https://blogs.mathworks.com/loren/2016/10/24/matlab-arithmetic-expands-in-r2016b/, but never incorporated into CVX.
You can use `repmat to accomplish what you want.
It worked perfectly. Thank you !
