Just trying to add an extra column to check1 (which has 4 rows) for both layers of dim 3, so I figured I could just concatenate it with the 4x2 matrix check2.
MWE:
Random.seed!(1)
check1 = rand(4,3,2)
[:, :, 1] =
0.236033 0.488613 0.251662
0.346517 0.210968 0.986666
0.312707 0.951916 0.555751
0.00790928 0.999905 0.437108
[:, :, 2] =
0.424718 0.251379 0.0769509
0.773223 0.0203749 0.640396
0.28119 0.287702 0.873544
0.209472 0.859512 0.278582
check2 = rand(4,2)
4×2 Array{Float64,2}:
0.751313 0.0856352
0.644883 0.553206
0.0778264 0.46335
0.848185 0.185821
check3 = cat(check1,check2,dims=(1,3))
ERROR: DimensionMismatch("mismatch in dimension 2 (expected 3 got 2)")
What I was expecting:
4×3×2 Array{Float64,3}:
[:, :, 1] =
0.236033 0.488613 0.251662 0.751313
0.346517 0.210968 0.986666 0.644883
0.312707 0.951916 0.555751 0.0778264
0.00790928 0.999905 0.437108 0.848185
[:, :, 2] =
0.424718 0.251379 0.0769509 0.0856352
0.773223 0.0203749 0.640396 0.553206
0.28119 0.287702 0.873544 0.46335
0.209472 0.859512 0.278582 0.185821
Edit: corrected 'expected check3’
