May 25, 2014 · %lu is correct, while %ul is incorrect. A printf format specifier follows the form %[flags][width][.precision][length]specifier. u is a specifier meaning "unsigned decimal integer". l is a length modifier meaning "long". The length modifier should go before the conversion specifier, which means %lu is correct.

Dec 31, 2012 · I can try to use macros to try to choose the correct string (#define LU either %llu or %lu, and in the process uglifying the printf strings a bit) but on the Mac I've got a 64-bit word size (so _LP64 would be defined and UINTPTR_MAX != 0xffffffff) and yet it …

Jul 29, 2022 · 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. CppCheck complains about it, but both work for both types in my experience.

Nov 14, 2015 · Therefore, \p{Lu} will match an uppercase letter that has a lowercase variant. And, the opposite \p{Ll} will match a lowercase letter that has an uppercase variant. Concisely, this would match any lowercase/uppercase that has a variant from any language:

Dec 17, 2013 · what does lu mean in this context: size_t size = 10lu; I have found nothing about it. Thank you!

Jul 9, 2010 · @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.

I want to implement my own LU decomposition P,L,U = my_lu(A), so that given a matrix A, computes the LU decomposition with partial pivoting. But I only know how to do it without pivoting. Can anyon...

LU decomposition without pivoting is rarely seen in practice. It's primarily used to introduced people to the idea of the technique, then the introduction builds by introducing pivoting. Pivoting with LU is what is used the most often.

Mar 9, 2013 · I am trying to implement my own LU decomposition with partial pivoting. My code is below and apparently is working fine, but for some matrices it gives different results when comparing with the built-in [L, U, P] = lu(A) function in matlab
