Métodos numéricos en simulink
Tengo una tarea de resolver analíticamente una ecuación diferencial por el método de Euler (lo hice con maltab) con su gráfica, y luego hacer diagrama de bloques en simulink para ver la gráfica nuevamente con un scope. Soy completamente nueva en simulink y el profesor no lo explicó por lo que quería ver si alguien puede ayudarme
El código de matlab es el archivo "Euler_analitico01.mlx"
Me da la gráfica:

Power Pivot running total without date column – NOT in Power BI
Hi all,
I am using Power Pivot in Excel and want to calculate the running total without Date column.
I found the following tutorial, which is for DAX in Power BI and tried to convert this to Excel Power Pivot but I am not able to do so.
Please can you help me converting this so that I can use it in Excel.
https://www.antmanbi.com/post/how-to-create-running-total-on-non-numeric-fields.
I am attaching a sample data table.
Running Total Brands =
VAR CurrentBrandSales =
[Total Sales]
VAR BrandsWithSales =
ADDCOLUMNS (
ALLSELECTED ( Products[Brand] ),
“@Sales”, [Total Sales]
)
VAR BrandsWithHigherSales =
FILTER ( BrandsWithSales, [@Sales] >= CurrentBrandSales )
VAR Ranking =
— Used only for confirming the ranking
COUNTROWS ( BrandsWithHigherSales )
VAR Result =
SUMX ( BrandsWithHigherSales, [@Sales] )
RETURN
Result
Thanks,
Naveen

Maximizing Spectral efficiency instead of maximizing SINR in RI selection in 5G NR toolbox
Hi all,
I’ve noticed that the new version of the 5G Toolbox includes two different algorithms for calculating Rank Indication (RI): ‘MaxSINR’ and ‘MaxSE’. The ‘MaxSINR’ algorithm selects the RI based on maximizing the SINR, while ‘MaxSE’ selects it based on maximizing spectral efficiency.
I was under the impression that the standard approach was to select the rank that maximizes SINR. Could anyone clarify the rationale behind including both algorithms and when one might be preferred over the other?

Why does the value of “PRBSetType — PRB allocation type” change to (VRB) through code even if I set it as (PRB) in the configuration?
Why does the value of "PRBSetType — PRB allocation type" change to (VRB) through code even if I set it as (PRB) in the configuration?
Specifically, "getPXSCHobject" function doesn’t read the input value of "PRBSetType — PRB allocation type" and always sets it by default value (VRB).
And as a result, code always go through one case of the two possible cases -PRBsetType = VRB-, so we can’t get the results when we want to set PRBsetType as (PRB).
The two possible cases are inserted below:
Case 1: PRBsetType = PRB
Case 2: PRBsetType = VRBWhy does the value of "PRBSetType — PRB allocation type" change to (VRB) through code even if I set it as (PRB) in the configuration?

Average code length and entropy
Hello,
I have an uin16 vector and I got the Huffman code from the built-in functions in MATLAB. The thing is that the entropy of this file is different from the average code length that I’ve got from the Huffman code. Isn’t the average code length supposed to be equal to the entropy of the file?

Data Unload from Snowflake to ADLS gen 2 using adf
Hi Everyone,
I am trying to unload data from snowflake into our Azure ADLS Gen 2 container using ADF. In ADF, I am trying to create a new linked service for the sink on ADLS Gen 1 and using ADLS Gen 2 SAS URI, if I directly use the SAS credentials it gives me a warning saying it Will publish immediately to our main branch, to avoid this I even tried putting the SAS credentials under our key vault and retrieving from key vault this way it would not publish to the main branch immediately. But even after this, I get an error saying the SAS URI is not constructed in proper format in Key vault, have followed the syntax shown in the error as well. Still doesn’t work, any suggestions or help is greatly appreciated.
thank you!

how to set initial signal out from relay simulink

this relay block switch on when the value reach 100 and the output signal is 1 and switch off when reach 20 and the output signal is 0.
my problem is that the relay initial output is always off, this means when the initial value is for example 44 the out out is 0.
but in some cases I want to be my initial output is on (1)
