hi,

i try to understand how to work with alglib package in order to solve linear equation Ax = b
so i copied the example of the solver for dense matrix using the rmatrixsolve fuction and the solver of sparse matrix using the sparsesolvesks function, and i built my own matrix A and vector b,

the first method gave me the right answear, the latter gave zeros,
i don't know why, can i get some help?


adding the cpp files
thanks
