2014年5月25日 · %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.

2022年7月29日 · 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.

2015年11月14日 · 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:

2013年3月9日 · 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

2010年7月9日 · @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.

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.

2008年12月16日 · GUID technically stands for globally unique identifier. What it is, actually, is a 128 bit structure that is unlikely to ever repeat or create a collision.

2022年2月11日 · Alternatively, assuming that M has an LU decomposition, we could do the following: [L,U,P,Q,D] = lu(M); L = L*P'*D*Q'; This should yield a lower triangular L and upper triangular U where U has 1's on the diagonal whenever M has an LU decomposition.
