i'm working on algorithm requires math operations on large matrix. basically, algorithm involves following steps: inputs: 2 vectors u , v of size n for each vector, compute pairwise euclidean distance between elements in vector. return 2 matrix e_u , e_v for each entry in 2 matrices, apply function f. return 2 matrix m_u, m_v find eigen values , eigen vectors of m_u. return e_i, ev_i = 0,...,n-1 compute outer product each eigen vector. return matrix o_i = e_i*transpose(e_i), = 0,...,n-1 adjust each eigen value e_i = e_i + delta_i, delta_i = sum elements(elementwise product of o_i , m_v)/2*mu, mu parameter final return matrix = elementwise sum (e_i * o_i) on = 0,...,n-1 the issue i'm facing memory when n large (15000 or more), since matrices here dense matrices. current way implement may not best, , partially worked. i used rowmatrix m_u , eigen decomposition using svd. the resulting u factor of svd row matrix columns ev_i's, have manually transpose rows...

this warning on publish, dotnet command... i'm unsure how resolve. dependancies riddled yellow warning symbols (after moving 2.0). when drilling down ends dependancy on newtonsoft.json in turn references system.runtime.serialization.formatters . anyone else have this, resolves it? error warning nu1603: restsharp.netcore 105.2.3 depends on system.runtime.serialization.formatters (>= 4.0.0-rc4-24217-03) system.runtime.serialization.formatters 4.0.0-rc4-24217-03 not found. approximate best match of system.runtime.serialization.formatters 4.3.0-preview1-24530-04 resolved.
