The mainqr_code()function returns an object of theqr_codeclass. This is a logical matrix with specific methods for printing and plotting. The print version uses UTF-8 drawing symbols and the result depend on the font used. For a better quality QR code it best to useplot()orgenerate_svg...

For full decompositions, qr(A) returns Q as an m-by-m orthogonal matrix satisfying QHQ=QQH=Im. For rectangular A with m > n, the economy-sized decomposition qr(A,"econ") computes only the first n columns of Q and first n rows of R. The columns of Q form an orthonormal basis fo...
