Hi,

How can I tell matlab to give me the result in desired form.

I'm using symbolic tool box.

For example, I got following transfer function from the symbolic tool box calculation

G=D*R*1/(C*L*R*s^2+L*s+R)

but I want matlab to represent the same function as follows

G=G_s*1/(1+s/(Qω_c )+(s/ω_c )^2 )

Where

 G_s=D
ω_c=1/√LC
Q=R*√(C/L)

Also find the attached.

Thanks.

Some of that looks like partial fraction analysis. The rest of it looks like using children() to extract sub-expressions.

Thanks, I'll try this.
