I am not familiar with mathematica syntax. I have this code which is written .np and I would like to translate it efficiently to Maple syntax.I tried FromMmaNotebook but it is not helpful for me. I would be grateful if you would give me a little help me translate the code. I attached the code as diagon.txt (you can change .txt with .nb)

Thank you in advance!diagon.txt

 

Hey!
I am using the solve function and I get the following form of the result :

rootsq0 := {z = 9.096986124+3.141592654*I}, {z = 1.138376998+3.141592654*I}, {z = .3074241220+3.141592654*I}, {z = .5854971300+3.141592654*I}, {z = -2.519351300+3.141592654*I}, {z = -5.138371980+3.141592654*I}, {z = -1.759344122+3.141592654*I}, {z = -0.9698634104e-1+3.141592654*I}

I want to convert rootsq0 into a list [9.096986124+3.141592654*I, 1.138376998+3.141592654*I, ...]. So, I would like to remove {} and z=. Any suggestions are welcome! :)

Hello,
I am trying to compute the convolution integral numerically and compare the result with the analytic result. My numerics is giving terrible results:

Hey everyone,

f_1 and f_2  are satisfying the set of non-linear integral equations I have attached to this message.
I know that I need to solve them numerically by iterations. Probably, the first guest of the function f_1 and f_2  is the driving term. a is just a parameter which can be fixed (I guess smaller than \pi/4). * is the convolution product and k is the momentum space parameter. I learnt that in order to solve them I should solve them in the Fourier space. I know also that I need to discretize these function in the “real ” space between {-L,+L} before applying the FFT or one of its relatives. Thank you for any suggestions or leads.

Hey everyone!
I have to solve this nonlinear system of equations . For small N (N=8), I tried to do it using solve but it is run forever. I have choosed \gamma to be equal to Pi/4.
