backwards compatibility 2020B to 2018B

hello fellow mathworkers,

I recently particpated in a mathworks MLBE Course with the 2020B Version with Simon Silge, and had a lot of fun.

currently I am using 2018B Floating license and I would like run some livescripts designed on the 2020B version.

the Livescript turns in to some mumble, which is hard to deceipher what is written there.

I can make it up what is written there but thats not the point.

is there someway to circumvent this problem?

I dont have the resources for a 2020B license

if you want to check: the allHist.mlx is not directly related but it is designed on the 2020B version. please run this on the 2018B to see if the problem occurs at your version of Matlab as well.

thanks for looking into this.

I added a link to the course that I guess you refer to.

We cannot run you script, since we don't have the data files, EuropeFertility and AfricaFertility.

I guess, your problem is caused by the character encoding of these data files.

and how do I solve this?

this occurs also by my own written files.

[per isakson]

I cannot run Chapter8.mlx, because I don't have the data files EPLteams.xlsx and EPLresults.xlsx.

With R2018b I saved Chapter8.mlx as Chapter8_18b.mlx. Matlab warned that info would be lost. The size on disk of Chapter8_18b.mlx is less than a third of the original file. I guess the data of the data files are stored internally in Chapter8.mlx and lost when saved in R2018b.

I cannot see any reason why your script wouldn't work with R2018b, but not without the data files EPLteams.xlsx and EPLresults.xlsx.

Caveat: I very seldom use the Live Editor.

thats not the problem...

they are just notes.... these are just notes i made during the course.

somehow the livescript has Compabitility problem with the 2020B version live script.

the notes are just an example. I would like to use the livescript from the 2018B instead the 2020B, because I just have a license for the 2018B

Communication is difficult.

"thats not the problem..." What is not the problem? The statements

teaminfo = readtable("EPLteams.xlsx","TextType","string") 
EPL = readtable("EPLresults.xlsx","TextType","string")

are my problem, since I don't have the excel-files.

Yes, all livescripts of R2020b are not possible to run with R2018b. That's clearly stated by The MathWorks. Thus the question is whether it's feasible to modify your livescripts so that they can be run on R2018b.

thanks Per Isakson,

for pointing that out that 2020B is not compatible with 2018B
