I am working with a code that first defines a matrix and then changes some values of that matrix. For example: temp1 = zeros(5,5); temp2 = temp1; temp2[[1; 3]] = [4; 3]; I would expect that the values of matrix temp1 would remain unchanged. But somehow the values of matrix temp1 are the same as…

As Oscar says, temp2 = temp1 just creates a new variable temp2 that is a different name for temp1, not a new underlying object. Consider: julia> t1 = zeros(5, 5); julia> t2 = t1; julia> t2 === t1 true help?> === search: === == !== ===(x,y) -> Bool ≡(x,y) -> Bool Determine whether x and y…
