Reference a variable in a text portion of a live script

Let's say for example I have a live script that calculates the square root (or any function) of some number x and returns it as y

Is it possible for the live editor to be able to grab the value of x and y and use them as strings in the formatted text? (using sprintf or similar?)

I do not care about this within the editor itself, but it would be nice to include this with the PDF or Latex code export

Example

x = 4;
y =sqrt(x);

Output:

"The square root of x is y" ← should be replaced with "The square root of 4 is 2"

Thanks!

x = 4;
y =sqrt(x);
fprintf('the square root of %g is %g',x,y)

I think that does it, it works on normal scripts too, the %g represents a numeric variable that you then call in the order they appear at the back of the function, but you can use many others, the formatting optins are here:

Thank you for your interest in this feature. This is something our development team is aware of and is considering.

This feedback is useful and we hope to address it in an upcoming release.

I would also really like this feature it would make the live editor much more usefull for presenting information in a format other than plots

Any update about this? Was trying to do the same

[Cecilia S.]

x = 4;
y =sqrt(x);
fprintf('the square root of %g is %g',x,y)

the square root of 4 is 2

Any update?

I'll send an update next week. Please excuse the waiting time.

A beta version for

1) creating handouts in the form of interactive live scripts,

2) creating handouts in the form of non-interactive documents,

e.g., as PDF, LaTeX, HTML, or Microsoft Word handouts,

is available for MATLAB's Live Editor.

Referencing MATLAB variables is possible with interactive live scripts and non-interactive documents.

Thank you.

Yes this is a basic function if you woul like to use live editor in a meaningful way to present data.

[Cecilia S.]

x = 4;
y =sqrt(x);
fprintf('the square root of %g is %g',x,y)
the square root of 4 is 2
