Whats the difference between %ul and %lu C format specifiers? But using %lu solved the issue Actually, rather than focusing on the problem and the line of codes, I want to know about the difference between %ul and %lu Maybe I could figure out what's wrong Searching doesn't give me something useful (except that "they are different") Any explanation or link reference is appreciated
printf - Difference between %zu and %lu in C - Stack Overflow What is the difference between %zu and %lu in string formatting in C? %lu is used for unsigned long values and %zu is used for size_t values, but in practice, size_t is just an unsigned long
Difference between numpy. linalg. solve and numpy. linalg. lu_solve Indeed you are right: chaining scipy's scipy linalg lu_factor() and scipy linalg lu_solve() is perfectly equivalent to numpy's numpy linalg solve() Nevertheless, having access to the LU decomposition is a great advantage in practical situations First, let's proove the equivalence numpy linalg solve() states that: The solutions are computed using LAPACK routine _gesv Indeed, the github
The necessity of LU decomposition (using numpy as an example) I am trying to understand the necessity of LU decomposition using numpy and scipy libraries From what I understand is that we want to solve Ax = b, we first factorize A into two triangular matrice
c - Usage of zd vs lu for sizeof - Stack Overflow I understand that %zd is the suggested way to format the sizeof result However, I don't understand why that is necessary For example using lu gives me the same output, and isn't the result of siz
python - What does scipy. linalg. lu return? - Stack Overflow A = P L U It is entirely expected that multiplying the P, L, and U matrices should produce something close to the array originally passed to scipy linalg lu You are not supposed to invert P
How to printf unsigned long in C? - Stack Overflow @Anisha Kaul: %lu is a valid conversion specification, %ul is not %lu, broken out is: % — starts a "conversion specification"; l — the length modifier, l means " [unsigned] long int"; u — the conversion specifier, u is for an unsigned int to be printed out as decimal Because we gave the length modifier l, it then accepts an unsigned long int The letters must be in that order: percent
How do you format an unsigned long long int using printf? My number is 8 bytes wide and its value is 285212672l A normal number is 0 I assume this unexpected result is from printing the unsigned long long int How do you printf() an unsigned long long int?
