Attempt at solution
This is an old exam question. Am I correct to say the shortest path goes through M since M is in d(O,M) and d(D,M)?
I don't know how to prove this and answer the question about the cost

Hi
I have a demand for 6 quarters of [29, 24,32,21,31,21] and can produce 25 units each quarter.
I am trying to calculate how many units I have to deliver at least 1 quarter too late and also how many units I...
I'm trying my first design and want to make it successful before I actually make the product.
I want to calculate what the stresses are and where they are likely to be.
F is a varied load from -10 to 10 kN
To find the critical points, should I check the points that i labeled A, B , C ...

Thanks. I copied the problem from a pdf i found online to post here. But I guess they changed the numbers in the problem cause it's not the same numbers as in my book. So the solution manual doesn't show the correct answers to my book even though they are the same editon.

Cany anyone help me with this. Can wolfram alpha do it? It has so many values and I'm not comfartble with doing 4th derivitives
I'm trying to make a banded matrix in MATLAB like the one in my picture.
I'm trying to use the spdiags function but I'm not going even close to getting the same matrix.
I have tried the help in Matlab but have had no luck yet.
How can you tell the bandwidth is 7?
The box signal is just like a rectangle plotted with stem. i really don't have the formula but it just a vector with a few ones in it.
No i get to choose all my N,N1 and N2 values. But i have to justify why i choose them.
It's just to test the fft function
Hi
I'm trying to use the fft function in MATLAB to compute the discrete Fourier transform of a box signal. I'm told to assume that the signal x[n] is periodic with period N and the vector contains one period.
x[n]= box [n]
I'm am going to use these commands to make my vector...
Discrete signal x[n] is shown in the first picture. Sketch x[2n]
Answer
Can anyone ecplain why x[2n] is like that. I can understand how to plot it if i have a continuous time signal
