I have the following code snip: a = Matrix(dR') b = W @show size(a),size(b) @show typeof(a), typeof(b) G = a*b This is the output/error I get: (size(a), size(b)) = ((1, 5), (5, 4096)) (typeof(a), typeof(b)) = (Array{Float64,2}, Array{Float64,2}) ERROR: LoadError: DimensionMismatch("dimens…

Can you please post a code to generate your matrices?

Its a bit complicated for me to provide code to generate the matrices, these are the matrices if I print them out though: a = [-218.83661398333524 -361.8123414207717 166.41607814303595 -85.62425321179961 -318.313315175026] b = [0.035196156028309326 -1.587458181822493 -1.2440061809684893 -0.83541530…

Works for me: julia> A=rand(Float64,5,1) 5×1 Array{Float64,2}: 0.2666400804573059 0.013809823633287754 0.02029482496653645 0.29355225061851464 0.4603132933757301 julia> a=Matrix(A') 1×5 Array{Float64,2}: 0.26664 0.0138098 0.0202948 0.293552 0.460313 julia> b=rand(Float64,5,4096) 5×4096 …

Note that your error message is from - not *, so perhaps the next step is the problem, rather than G = a*b? [image] Tommaso_D_Amico: [3] -(::Array{Float64,1}, ::Array{Float64,1}) at .\arraymath.jl:38
