Solve Error in Symbolic Matrix

hİ, solver returns this for syms matrix forms. How should I use solver?

syms K11 [3 3] matrix
syms deltat [1 1] matrix
solve([K11+K11==deltat*K11],[deltat])

gives

Check for incorrect argument data type or missing argument in call to function 'solve'.

Why are you writing matrix while defining the variables?

[Ahmet Parker]

in R2021a this is a new option. They are matrices and matlab applies martix rules. And they are symbols

[Dyuman Joshi]

Oh, Don't know about that. Anyways, here's what I have done. Is this what you want?

[Ahmet Parker]

No, thank you very much

[Walter Roberson]

solve() is not defined for symmatrix() yet.

solve(symmatrix2sym([K11+K11==deltat*K11]),symmatrix2sym(deltat))

Apologies for hijacking the problem, but is there a way to know what new functions have been to added to the latest version of MATLAB? @Walter Roberson

[Swatantra Mahato]

@Dyuman Joshi as far as I am aware you can get information on new features and funcitons in a toolbox from its Release Notes

[Dyuman Joshi]

@Swatantra Mahato How to know which toolboxes have been introduced with the newest release? In the release notes of the version?

[Walter Roberson]

https://www.mathworks.com/products/new_products/latest_features.html

In R2021a, the new toolboxes are:

• DDS Blockset - Design and simulate DDS applications
• Radar Toolbox - Design, simulate, and test multifunction radar systems
• Satellite Communication Toolbox - Simulate, analyze, and test satellite communications systems and links

[Dyuman Joshi]

@Walter Roberson Thank you for the link, it is exactly what I was looking for!

Hi Ahmet,

You can execute the following command (as mentioned under Limitations section for the "symmatrix" funciton) to find the functions which currently accept symbolic matrix variables as input

methods symmatrix

solve currently does not support symbolic matrix inputs (as also mentioned by @Walter Roberson)

Hope this helps
