Hi, you can't solve this without future assumptions because in you P-matrix are m x m unkowns but you have only m-equations v[n]==v[0].P^n and so yo miss m^2-m equations and this seems a bit too mutch. Regards Jens "Ramier" <wissam2 at online.fr> schrieb im Newsbeitrag news:dd9nas$j1h$1 at smc.vnet.net... | Hi everyone, | | I've got some linear equations to solve and I don't really know how to | do it | Is it possible to solve such an equation with Mathematica : | | v_n=v_0.P^n | | where v_n and v_0 are two vectors of m-components and P is a mxm matrix | (in the problem i'm studying, m is about 100).
