Consider the code below. function dummy() A = zeros(2,2) for i=1:2 for j=1:2 A(i,j) = rand() # should be A[i,j] end end return A end It returns julia> A=dummy() A (generic function with 1 method) which is very weird, since in the REPL writing A(i,j) in…

Never mind! I figured it out. It’s the inline function definition syntax tripping me up. A(i,j) = rand() is defining a function that maps its 2 args to a random number. This is a nasty “gotcha” for ex Matlab prorgammers to be aware of!

A(i,j) instead of A[i,j] leads to weird behavior
