Functor for the NORMCOL projector.
A, the image matrix, is defined by \( \forall j \in \{1,\ldots,shape(2)\} \) the j-th column \( A_{*,j} \) is such that \( \| A_{*,j} \|_2 = s \).
Usage
normcol(shape, s): returns a NORMCOL projector (functor), shape defines the size of the input matrix (e.g. [1, 10]), s defines the sparsity of the output matrix (the 2-norm of each column).
shape | vector of size 2, to define the size of the input matrix. |
's',value | (optional) the sparsity parameter, the 2-norm of the column (1 by default). |
normcol | projector |
