Increment value and run for cells missing in R2021b

Has the "Increment and run" feature for code in the editor been removed in 2021b? I understand that live scripts implement it but its clunky for what I want to do.

We are happy to report that starting in R2023a, the Increment Value and Run Section tool is once again available in the Editor. You can use the tool to increment, decrement, multiply, or divide numeric values in the Editor and then run the current section after every change.

To adjust a numeric value, select the value or place your cursor next to the value, right-click and select Increment Value and Run Section. Then, use the Increment Value and Run Section dialog box to adjust the value and run the current section.

The Increment Value and Run Section tool is only available in the Editor. To adjust numeric values in the Live Editor, use controls such as numeric sliders and spinners.

For more information, see Create and Run Sections in Code and the MATLAB Release Notes.

Thank you so much !!

Hi Chris,

You are correct that Increment Value and Run Section tool has been removed in R2021b, checkout release Notes

To increment a numeric value within a section, use controls in the Live Editor. For example, this code calculates the factorial of the variable x.

x = 5;
y = factorial(x)

y = 120

To interactively change the value of x, in a live script, replace the value 5 with a numeric slider. By default, MATLAB reruns the current section when the value of the slider changes.

For more information, see Add Interactive Controls to a Live Script.

This solution is not applicable in the normal editor. Why the feature was removed in the normal editor?

[Martin Vesely]

Indeed. Why this feature is missing in normal editor (2021b)? I really think about downgrading back to previous matlab version.

Please, put the feature back!

[Zeb Barber]

I agree, I used this feature all the time. The live editor is so slow compared to running scripts in the standard editor

[Dario Bosch]

I'm totally with you. While I like some of the changes in 2021b, this is awful. Live editor isn't really a good replacement to the conventional editor...

[CdC]

PLEASE PUT INCREMENT AND RUN BACK in the next release! This is a very important feature. We're not able to use the latest matlab versions of everything because of this. Don't decide for your users that they don't need this long-loved feature. Thank you.

Such a shame that they've removed such a crucial feature!

I'm also missing this feature... Just tried the control in the live script, but this is no alternative for me.

[Matthieu]

Really a pitty... missing feature...

This feature was removed a little too quickly, which is a bit of a shame.
