@david Hello Sir, First of all thank you for your kind concern to my proposal. For uBLabs, As I go through the ideas and page, then i see that many challenges are quite interesting projects, and can be done. I would like to work in matrix and vector handling Regarding this here is what I understand and my thought. As its true linear algebra so we have to go as in maths so if we have to multiply two vectors then as it can be represented in matrix (row matrix or column matrix ) form so first of all we have to convert into one form then we have to multiply both the matrix and then convert back to vector form. Simmilarly * can be done with two matrices or one matrix and one vector. For implementing this in c++ we would be needing classes for defining various properties and methods for matrix and vectors. I can be more specific if I know what developments in this have been done, so that we can start with that. with many thanks and regards, Niranjan Singh
