> TL;DR, answer: to get a 2x1 Array/Matrix transpose a 1x2 matrix, for example: [2 4]' A more general solution that also works for complex numbers in Julia V0.7- would be transpose([2 4]) I wanted to test julia\> maximum([1 2; 3 4], 2) 2×1 Array{Int64,2}: 2 4 So I tried julia\> maximum([1 2; 3 4], 2) == [2;4] false I expected the value to be true, but the value is false because julia\> [2;4] 2-element Array{Int64,1}: 2 4 That is, a 2×1 Array{Int64,2} is not the same as a 2-element Arra…

> Much gnashing of teeth derives from the overlap between syntax for array literal… construction and array concatenation in Julia – largely inherited from Matlab. Perhaps we should just use a different syntax for block matrix construction entirely. One thought would be this:

> c d |

> This has the advantage of being pretty terse and lightweight. For example, the current idiom of expanding a range into an array is \`\[1:10\]\` which would become \`|1:10|\` while \`\[1:10\]\` would construct a one-element array of type \`UnitRange{Int}\`.
