Hello,
I'm trying to define a function x1=-c1/b1*x2+d1/b1, where b1,c1,d1 are defined, but x2 should be kept as a variable. Here's how it all looks at the end

You can do that with Anonymous Functions:
x1 = @(x2,b1,c1,d1) -c1./b1.*x2+d1./b1;
if you want to include all the constants as arguments,
or:
x1 = @(x2) -c1./b1.*x2+d1./b1;
if you want to pick the constants up automatically from the workspace.

Wow! That was quick. It only took you 7 minutes to answer, this other program that I've been using has a way slower community. The anonymous function works great. Though before posting, I tried searching for a similar post and in my findings encountered the anonymous function, without your help I couldn't properly understand how to apply it to my code. Thanks a million!
