I wanted to generate dates with wrong values like 30/02/2022. How to do it?
I used generate rows step in transformation with add sequence and calculator but it is showing all values correct. I want to include incorrect values to filter out it in next step.

On one sheet, I have account code and in the cell next to it, I need to look up the account code on the next sheet to average the cost excluding those cells that are zero in col. b from the average calculation.
The answer for London should be: £496.33 but having tried various sumifs / countifs I cannot get it to work.
You probably need COUNTIFS which -- similar to the SUMIFS you are already using -- allows to define multiple critera and ranges.
So, if the column R contains the values, you want to build the average upon, and the column H in the respective row must equal $B$28 to be included in the sum, the respective COUNTIFS looks as follows
=SUMIFS('ESL Info'!$R:$R,'ESL Info'!H:H,$B$28)/COUNTIFS('ESL Info'!$H:$H,$B$28, 'ESL Info'!$R:$R, "<>0")
ie additionally to the value in the H-column to equal B28 it also requires the value R-column (ie the actual number you are summing up) to be different from 0
You could also add the same criteria 'ESL Info'!$R:$R, "<>0" to your SUMIFS, but that isn't necessary, because a 0 doesn't provide anything to you sum, thus it doesn't matter if it's included in the sum or not ...
And depending on the Excel version you are using, you may even have the AVERAGEIFS function available, which does exactly what you want
=AVERAGEIFS('ESL Info'!$R:$R,'ESL Info'!$H:$H;$B$28,'ESL Info'!$R:$R,"<>0")
I am attempting to use the ZN() function to detect any NULL values, but the measures I need to use are categorical.
They can either only hold one of two values (Valid or Invalid) or be blank.
Is it possible for Tableau to treat these categorical values as numerical?
My first thought was to use a factorisation-type function, like the one in R, but I am not aware of any such function in Tableau.
Can this be achieved?
Create calculated field with following formula
CASE [YOUR_FIELD]
WHEN NULL THEN 0
WHEN 'Invalid' THEN 1
ELSE 2 END
I am very new to MATLAB. I am sorry if my question is basic. I am using "printmat" function to show some matrices in the command console. For example, printmat(A) and printmat(B), where A = 2.79 and B = 0.45e-7 is a scalar (for the sake of simplicity).
How do I increase the precision arbitrarily to seven decimals? For example: my output looks like 2.7943234 and B = 0.00000004563432.
How do I add a currency (say dollar) figure to the output of printmat?
How do I add a percentage figure (%) to the output of printmat?
Note: The reason I use printmat is that I can name my rows and columns. If you know a better function that can do all above, I would be glad to know.
Regards Mariam. From what I understand, you would like to display the numbers and show their full precision. I am also newbie, If I may contribute, you could convert the number data to string data (for display purposes) by using the sprintf function.
I am using the variable A=2.7943234 as example. This value will not display the full precision, instead it will display 2.7943. To show all the decimal tails, you could first convert this to string by
a = sprintf('%0.8f',A);
It will set the value a to a string '2.79432340'. The %0.8f means you want it to display 8 decimal tails. For this example,%0.7f is sufficient of course.
Another example: A=0.00000004563432, use %0.14f.
A=0.00000004563432;
a=sprintf('%0.14f $ or %%',A);
the output should be : '0.00000004563432 $ or %'.
You could analyze further in https://www.mathworks.com/help/matlab/ref/sprintf.html
You could try this first. If this does not help to reach your objective, I appreciate some inputs. Thanks.
The printmat function is very obsolete now. I think table objects are its intended successor (and functions such as array2table to convert a matrix to a table of data). Tables allow you to add row and column names and format the columns in different ways. I don't think there's a way to add $ or % to each number, but you can specify the units of each column.
In general, you can also format the display precision using format. Something like this may be what you want:
format long
I have a text file with two columns: "date" and "cumulative value". I'd like to difference "cumulative value", as a calculated field in the data source.
I cannot even get a lag value:lookup([cumulative value],-1) produces an error.
Thank you.
There are two things you can do.
Create a new field with the following formula:
SUM([cumulative value])-LOOKUP(SUM([cumulative value]),-1)
Tableau requires an aggregation for you to use the LOOKUP function. Hence why I used the sum function. Then you could plot that against DAY(Date).
OR
Plot DAY(Date) against SUM(cumulative value), then right click SUM(cumulative value), click Quick Table Calculation, and then Difference. This can only be used/done in plots though.
I'm new to MATLAB. I have two values x and y. Both of them contain values with unknown accuracy. The problem: How could I display them both in one row with 2 digits after comma? Like:
x<tabulation or stack of spaces>y<then goes new line>
Example
RAW data
0,324352 0,75234
1,563 3,4556
Expected output
0,34 0,75
1,56 3,45
Upd: for one value it works well
disp('x=' num2str(x,3));
Purpose is: display TWO values on one row with the new line symbol
The answer is:
disp(num2str([x y],3));
The 3 value means - max.quanity of symbols after comma including it(am I wrong? just thoughts)
Another Idea:
Somehow represent X and Y as array values and then display them.
