Derivatives in Embedded Matlab

Derivatives in Embedded Matlab

Derivatives in Embedded Matlab

Hi there,

In Simulink, I'm trying to differentiate a function with respect to a non-time variable. So I created an embedded matlab function and wrote down the following:

function phi = func(B)
syms x;
phi = diff(cosh(B*x)-cos(B*x)...),x);

This function works if called from Matlab console, but with Simulink it complains that "command duality is not supported". What's the way to do it then?


RE: Derivatives in Embedded Matlab

Hi Greg,

The function is way longer than what I typed above, that's why I put the ellipsis :P
I might be able to differentiate it this time, is there an easier way though?


RE: Derivatives in Embedded Matlab

That was silly, never mind.
Thanks for the help.
