- matrix - LU Factorization for MATLAB - Stack OverflowAlternatively, 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.
- c# - What does this regexp mean - "\p {Lu}"? - Stack OverflowTherefore, \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:
- What's the difference between %ul and %lu C format specifiers?%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.
- printf - Difference between %zu and %lu in C - Stack Overflow%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. CppCheck complains about it, but both work for both types in my experience.
