It should be possible, in the future, to assemble the full matrix using the Julia package DiffEqOperators.jl We test the solver on the lid-driven cavity problem and compare results with Ghia & Ghia’s solution. Governing equations The governing equations are as follows: ∂ω∂t+(∇⊥...

创建一个临时的二维数组matrix,用于存储两个输入矩阵相乘的结果。...如果第一个矩阵的元素的列号等于第二个矩阵的元素的行号,将它们的值相乘,并将结果累加到matrix中对应位置的元素上。 遍历matrix中的所有元素,将非零元素插入到result中。 9910 Julia将成为编程语言黑马,是Python未来的劲敌?
另外就是我感觉Julia的一些设计导致它的第三方包经常没有向最优的方向发展。比如Julia的写DSL很方便,...
