Here's what worked for me just now on MATLAB 7.14: >>a=real(collect(3*R1*w*(RF + 200)/((R2*w*29*i + 3)*(3*R1*w - 2*i)))) >>b=imag(collect(3*R1*w*(RF + 200)/((R2*w*29*i + 3)*(3*R1*w - 2*i))))

FTR, I did figure out a very simple way to do it but at the cost of keeping y and z as symbolics. I created nested for-loops which let's me calculate the integral with quad for each pair of y and z values I'm interested in. This happens to work for me now but if anyone comes up with a better...

I'm having to do the same thing. I own several Matlab intros and references but the only one I've found really helped is Rudra Pratap's Getting Started with MATLAB. I used it to get the hang of arrays and basic operations. Once you have the basics, you can teach yourself and the rest kind of...

Could you post some equations to clarify?

Have you tried >>vpa(your expression) or >>simplify(collect(your expression,i))? The first will condense all your constants if they're given numerically, whereas the second will organize your symbolic expressions into coefficients of 1 and i (i.e. a and b). Hope that helps. Rebekah

I have a symbolic function of three variables which I'm trying to numerically integrate wrt a single variable. Consider (syms x y a) and the function f(x,y,z). Here are some things I've tried, without success: 1. >>int(f(x,y,z),x,a,b) which analytically integrates f wrt x from a to b but...
