A_ldiv_Bt
A_ldiv_Bt(A, B)
For matrices or vectors $A$ and $B$, calculates $A$ \ $Báµ€$
Examples
julia> A = [1 2 3; 4 5 6];
julia> B = [7 8; 9 10; 11 12];
julia> A_ldiv_Bt(A, B)
2×2 Array{Int64,2}:
58 64
139 154This example calculates the matrix product of A and Bᵀ, resulting in a 2x2 matrix.
julia> x = [1, 2, 3];
julia> y = [4, 5, 6];
julia> A_ldiv_Bt(x, y)
3×3 Array{Int64,2}:
4 5 6
8 10 12
12 15 18In this example, the function is used to calculate the outer product of vectors x and y, resulting in a 3x3 matrix.
Common mistake example:
julia> A = [1 2; 3 4];
julia> B = [5 6];
julia> A_ldiv_Bt(A, B)
ERROR: DimensionMismatch("matrix A has dimensions (2,2), matrix B has dimensions (1,2)")In this example, the dimensions of A and B are not compatible for matrix multiplication. Make sure the dimensions of the matrices or vectors are appropriate for the desired operation.
