    Graduate Solve for x, a and b in matrix equation aAx + bBx = C

    Thank you. :smile: I have read the forums for quite some time. Lots of interesting stuff and insight to be found. Yes, but I am not sure I understand the distinction between that and what I wrote? Please elaborate what I have misunderstood or stated unclear :-/? Thank you, but the problem...

    Thank you. You are correct. That is what I meant. Equivalent to using two 'cumsum' in Matlab.

    Graduate Solve for x, a and b in matrix equation aAx + bBx = C

    Hello everybody I recently encountered the following equation C(t) = a\int_0^t{x(\tau)d\tau} + b\int_0^t{\int_0^\tau{x(\tau')d\tau'd\tau}}, where C, a, b and x are greater or equal to zero. C and x are vectors - in my case around 3500 long - and a and b are constants. If we take...
