For laboratory work is required to test the program on big data. SLAU 100 dimension and even 1000. The question is where to get such ready SLAE or mb in math packages have the function to generate them? I did not find. Tell me please.

  • I would automatically generate the matrices of these SLAES, so that the matrix A is nondegenerate. - Alexander Muksimov

    In the first approximation, you simply define a random vector solution X and the identity matrix E Then, similarly to the Gauss method, only in the reverse order you multiply the rows by nonzero random numbers and add them. Guaranteed to get SLAE with exactly one solution. Probably not optimal, but 1000 is not such a large number, nothing better comes to mind, and the algorithm is no more complicated than Gauss. - Fat-Zer
  • A good idea! Thank. - beatsspam
