Description
Originally https://github.com/JuliaSmoothOptimizers/NLPModels.jl/issues/281 by @vepiteski:
My code breaks and I have no simple workaround. I can't construct the matrix which is implicit in the expression AcXAr' where X is a bitmap. The linear operator is constructed by reshaping the vector x to the matrix X and computing AcXAr' and then reshaping back the result to matrix format. The implicit matrix would be HUGE.
