psat :User Defined Models (UDMs)

I am using User Defined Models (UDMs) in PSAT to create a new type component . In order to deepen the understanding, I used PSAT examples for modeling. When I click on 'build' button，it displays:

Failed to initialize symbolic preferences.

> In syms (line 195)

In fm_build (line 96)

In fm_comp (line 66)

Cannot rewrite file "fm_ncomp.m". Check file permissions and content.

Did anyone know the reason and could please help me?

Hi @tony stank,

The error "failed to initialize symbolic preferences" originates because of issues with the installation of Symbolic Math Toolbox.

Symbolic Maths Toolbox included in Matlab R2017b and Matlab 2018a hangs or issues an error as mentioned in the following bug report: https://www.mathworks.com/support/bugreports/1755918

If you are using any of these versions, I recommend upgrading to latest version of MATLAB.

Hope this helps!

That bug report appears to be completely unrelated.

The following user seems to have a similar bug which he could solve by upgrading MATLAB version:
