MATLAB: Is the Embedded MATLAB Function block blue in Simulink 6.6 (R2007a)

Question

I have a custom library from which I take an Embedded MATLAB Function block into my model. This block's Foreground color is blue. When I try to change the color to black, it does not get saved, and the Embedded MATLAB Function block, stays blue.

Answer 1

Documentation on the Embedded MATLAB Function Block with respect to custom libraries is missing from 'Using the Embedded MATLAB Function Block' manual.

Here is additional information on the Embedded MATLAB Function block

Embedded MATLAB Function blocks taken from Custom libraries are colored blue. If the link to the library is broken, the block turns black.
