Queue?

[herdrick]

Hello -- I'm using the expressions language. I need queue functionality (push, pop). What you do you recommend? If I could use JS arrays that would be great. (#3550)

Try

config({matrix:"Array"})
a = []
a.push(1)

Or

a = [].toArray()
a.push(1)

Or you could try to import your custom functions according to your needs.

Assuming 1D matrices

a = []
a[end+1] = 10
a # [10]
a.resize([a.size()[1]-1])
a # []

And you could import your own push and pop functions.

math.import({
  push: (m, v) => {m.set([m.size()[0]], v)},
  pop: (m) => {m.resize([m.size()[0]-1])}
})

a = []
push(a, 10)
a # [10]
pop(a)
a # []

math.import({
  push: (m, v) => {m.set([m.size()[0]], v)},
  pop: (m) => {m.resize([m.size()[0]-1])}
})

I can't use this because I'm using the expressions language.

This is great, thank you!
