Как можно достичь показателей матрицы. например:
m
3×5 Array{Int64,2}:
1 2 1 2 3
1 2 3 1 2
2 2 2 2 0
is the matrix. for accessing indices in first row these functions used.
s=ind2sub(m,find( x -> x == 1, m[:,1] ))
([1, 2], [1, 1])
but for 2
s=ind2sub(m,find( x -> x == 2, m[:,1] ))
([3], [1])
it didn't find the fist 2 in indices[1,2]
and also for 3
julia> s=ind2sub(m,find( x -> x == 3, m[:,1] ))
(Int64[], Int64[])
there was not any indices.
for more explanation
indices are need to make y. y is made from m that is included binary elements. y[i=1:5,k=1:3,t=1:3]
y[:,:,1]=[1 0 0;0 1 0;1 0 0;0 1 0;0 0 1]
y[:,:,2]=[1 0 0;0 1 0;0 0 1;1 0 0;0 1 0]
y[:,:,3]=[0 1 0;0 1 0;0 1 0;0 1 0;0 0 0]
Не могли бы вы мне помочь, как можно достичь правильных показателей?
большое спасибо.
