QUESTION
Folks, Basically what I am expecting is a list of lists based on the input comma separated numbers. As you can see I have 5,6 which means I need to create a 5 lists with 6 elements and each of the element in the lists will have to be multiplied by the index position. So what I need from the below input is [[0,0,0,0,0,0], [0,1,2,3,4,5], [0,2,4,6,8,10], [0,3,6,9,12,15],[0,4,8,12,16,20]]
instead what I get is [[0, 4, 8, 12, 16, 20], [0, 4, 8, 12, 16, 20], [0, 4, 8, 12, 16, 20], [0, 4, 8, 12, 16, 20], [0, 4, 8, 12, 16, 20]]
not sure what I am doing wrong.. Can anyone please help?

QUESTION
I need to retrieve a range delimited by indexes from a specific array
I cannot use OFFSET because it doesnt use an array as a parameter. And the range will then be use for a secondary calculation
The example:
I want to calculate the SUM of the 4th to the 11th value in the column Numbers.
So at the end the formula should look something like:
=SUM(Numbers[4:10]) = 36
4 and 10 being the desired indexes.
I tried with OFFSET and INDEX but cant figure out how to do it.
...ANSWER
Answered 2021-Jun-16 at 02:36Index()
, INDIRECT()
will work. Also OFFSET()
will work but need to apply some trick. As @BigBen suggested you can use INDEX()
like =SUM(INDEX(B:B,5):INDEX(B:B,11))
but I am sure you will not prefer to hard code index no. So, you can use below formula to dynamically input two index and get sum between those index. Try-

I'm trying to decrease the bundle size of my Vue project, which scaffolded by the vue-cli, by using CDN of firebase, Vue, and Vuetify.

ANSWER
Answered 2021-Jun-16 at 01:31If you are using vuetify from vue-cli-plugin-vuetify
(vue add vuetify
), treeshaking and auto component import is enabled by default, by using vuetify-loader
.
If you look into the source code of vue-cli-plugin-vuetify
, it only uses vuetify-loader
if it is present in your package.json
. So removing vuetify-loader
from package.json
should disable this behavior.
QUESTION
I've stumbled upon a quite innovative functionality in editor – ability to TAB-complete symbols from CTags index, on this Asciinema video.
I wonder if there is anything like it available for Vim? I've been using many completion engines like eg. CoC, however none of them seems to offer what NeoMCEdit does. Is there such plugin for Vim?
...ANSWER
Answered 2021-Jun-15 at 21:01Basic keyword completion, :help i_ctrl-p
/:help i_ctrl-n
, already does that out of the box because of the default value of :help 'complete'
.
Alternatively, you can use your tags
files as exclusive source with :help i_ctrl-x_ctrl-]
.

QUESTION
I have a data frame including three columns named 'Altitude', 'Distance', 'Slope'. The column of 'Slope' is calculated using the two first columns 'Altitude', 'Distance'. @ the first step the purpose was to calculate 'Slope' using a condition explained below: A condition function was deployed to start from the top column of the "Distance" variable and add up (sum) values until the summation of them is greater or equal to 10 (>=10). If this condition corrects then calculate the "Slope" using the given formula: Slope=Average(Altitude)/(sum(Distance)). The summation of the 'Distance' was counting from the first value of that to the index that the 'Distance' has stopped there). The following code is for the above explanation (By Tim Roberts):

Answered 2021-Jun-16 at 00:46The issue you are having has nothing to do with templates. You cannot invoke std::async()
on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.
