WebMay 17, 2024 · 6. Stiffness matrices WANT to be sparse. Desperately so. The point is that these big stiffness matrices will end up with a huge number of zero elements. So you need to build the matrix with that in mind. The nice thing is that sparse matrices are very nicely supported in matlab. But you need to work with them properly. WebMy dynamic matrix structure is an array of SparseRow objects. The idea is to have objects that have both a size (number of used coefficients) and a capacity (number of allocated …
