This returns a single value but that's not what I want. I want the rms of each of the 10 matrices, result to be a 4072x22 matrix.

This might work, but I am looking for the RMS of not A(:,:,1), but all the 10 matrices..basically i have 10 4072x22 matrices put together in 1 3d matrix and I want the RMS of these 10 4072x22 matrices as one matrix..

I have a 4072x22x10 matrix. I am trying to calculate the RMS of the 4072x22 matrix but am unable to do so. The worst case scenario would be to individually calculate the RMS value of each element but that would require a number of loops and I don't want to do so. Is there any easier way to get...

I got the solution to the equation using the fourth order differntial, but am stuck wolving for the constants c1,c2,c3,c4. If I wanted the second order differntail for x1, would that be x1'' = c1 e^4t +c2 e^-4t ??

In order to solve for c1,c2,c3 and c4, I would need the second differential of x1. Would that be x1'' = c1 e^4t +c2 e^-4t ??

I am sorry, I was taking the second dervivative for some reason. I conclude that a = 2 would be thr right solution. Am I correct??

would a = 4 be the correct solution??

So the solution would be x1(t) = c1 e^(16t) + c2 e^-(16t) + c3 sin(16t) + c4 cos(16t)??

Solving fourth order differential equation (URGENT) I have two second order differential equation which needs to be solved. x1''(t) = 8 x2(t) x2''(t) = 2 x1(t) I have the initial conditions, x1(0) = 0, x2(0) = 1, and terminal conditions x1(pi/4) = 1, x2(pi/4) = 0. Can anyone help me...
