Julia SparseArrays.spzeros用法及代码示例

spzeros([type,]m[,n])

创建长度为 m 的稀疏向量或大小为 m x n 的稀疏矩阵。此稀疏数组将不包含任何非零值。在构造过程中不会为非零值分配存储空间。如果未指定，则类型默认为 Float64 。

例子

julia> spzeros(3, 3)
3×3 SparseMatrixCSC{Float64, Int64} with 0 stored entries:
  ⋅    ⋅    ⋅
  ⋅    ⋅    ⋅
  ⋅    ⋅    ⋅

julia> spzeros(Float32, 4)
4-element SparseVector{Float32, Int64} with 0 stored entries
