The multiplication of matrix

[Z-Z188]

Hello author, thank you very much for your work. But I have a problem with the multiplication of this matrix: if X is a matrix of size (d,b), then the transpose of X x X has size (b, b), and WX-X has size (d, b), then how can the two matrices be multiplied? Look forward to your reply, thank you!
