Indices in an array
Hello, I have a huge list of values in an array M(1432188,3). I need to compare two numbers (in the same column), when these two numbers are equal I need to know their indices. Does anyone know how to do that? Is there a built-in function capable of doing that? If someone can help me, it... -

Shifting array in the vertical direction
Hello, I have the following array a(1,:)=(/2.144999981, 2.144999981, 2.144999981/) a(2,:)=(/2.144999981, 2.144999981... -
sunsets of a set
Hi Mikrom, Thanks for the detailed explanation, I appreciate it. Regarding the file size, Yes it is huge. I need this code because I am writing a Monte Carlo Simulated Annealing (MC-SA) and I need to explore the arrangements of a particular crystal and each arrangement of 16 numbers [between... -
sunsets of a set
Dear xwb's, First of all, the code works perfectly and thanks for that. I just have some doubts due to my lack of experience in FORTRAN. 1.The 'i1' that you used in the loop, it is not specified in the variables section, and as far as I know it should be declared as an integer. It's clear... -
sunsets of a set
Hello, First of all thank you so much for your reply and time. I am going to check it and try to understand the meaning of these loops. I know how to use loops but this is the very first time that I see this notation in loops. Thanks again, I really appreciate it. -
sunsets of a set
Hello, I have not tried yet, I am a bit new in FORTRAN... so, if you could give me an example it would help me a lot. Thanks and kind regards, -
sunsets of a set
Hello everyone, I need to generate all the possible combinations of a set (in my case my set has 32 elements) and I need all possible subsets of 16 elements. So, anyone have any idea how to do this? There are subroutines and I have tried, however, documentation is not clear enough. So, if... -
generation of different random number
Hi, this is a code for FORTRAN 90, it will give you 10 random numbers, you can play with the loop. program aleatorio implicit none... -
periodic boundary conditions (PBC) using cshift function
Dear all, I have written a code for PBC for a cubic system, however, I need to implement PBC for a crystal lattice with different geometry (not cubic). I read that the cshift function might help, however, i feel lost regarding how to implement PBC using cshift function. My code for the cubic...
