I would like to define a certain function that takes a vector as input and does some computations that involving varying just one of the entries. For example, if the input vector is a, I would like to compute f(a) whlie “pretending” that a[1] = 0. One way to do this is b = copy(a); b[1] = 0, f(b), …

[image] maxkapur: let a = a, a[1] = m # do some computations on a @show a end Even if this were valid syntax, it wouldn’t do what you want anyway because let a=a doesn’t change the fact that a points to the same value, so mutating that array will still mutate t…

Is `let` the right tool for this task?
