Also, is there anything similar to the "Find()" function in MathCAD? Just curious. It's not necessary as I can program it in myself. EDIT: Also, I need to be able to get a result within a certain error. I would use ([result - actual value]/actual value)*100, except that the actual value co...

### More help with Matlab

Yep. I once again need some help. Though it's very simple (I hope) this time. Is there any way to use units in Matlab? I want to be able to specify units like I can in MathCAD and have it tell me the output units. It doesn't matter if this is done separately from the program, so long as any conversi...

### Help solving an equation symolically

I have an equation that has 2 unknowns. I want to solve for one unknown in terms of the other and have the answer in symbolic form. I have access to Mathcad 15 and Matlab R2010a, but I'm not sure if either of these are even capable of it. Example: z = (x-y)/(0.1 + (ln(a/b)/2*pi*l*k) + 1/h*2*pi*a*l) ...

Python doesn't have true global variables, only module-level variables. "Globals" defined in one module aren't visible in another. If module m defines a "global" v (just with something like v=10 outside of a function), then other modules that import m can refer to it via m.v , b...
