 Nov30 comment MATLAB Feedback @DanielR ya that is what I was reading but I still don't fully understand the extra 1,-1 Nov30 comment MATLAB Eigenvalues @Amzoti yep that worked. It still says -1/3 and 1 rather than -1 and 3 but that's good enough. Nov30 comment MATLAB Eigenvalues @Amzoti tbh, I saw that during my search and I have no idea what that is or what to do with it.... Nov29 comment Matlab calculate output but I want the user to be able to call the function and just type in something like "s^2+s+1" so how do I detect that and/or do the laplace transform of that? Nov29 comment Matlab calculate output I tried my function out by doing sys_response(s+1/(s^2+5s+6),ut) but it said Undefined function or variable 's'. Any idea how to fix that problem? Apr20 comment Matlab Cropping Plots yah I have no idea why it's not working. I've just went ahead and used this file to control whitespaces. But I'll mark this right since it works for you. Thanks! Apr20 comment Matlab Cropping Plots are the ellipses supposed to be there? I hope that's not a stupid question, I'm new to matlab so I'm not a 100% on the syntax yet. Also I changed the font size of the x and y axis labels along with the title, is that going to change anything? Apr20 comment Matlab Cropping Plots no that didn't work...i'm still getting some big whitespace on the left. Apr13 comment Matlab Index out of bounds @mathguy so i set out=zeros(4,1) and did out(4)=A; and i'm still getting the same error Apr13 comment Matlab Index out of bounds @mathguy of course but I don't see how A could possibly change... Apr13 comment Matlab Index out of bounds @Daryl but then it says too many input arguments Apr10 comment Non-linear Partial Differential Equations but the partial derivative of that with respect to $t$ does not give $\rho^2$....or maybe I'm taking the partial derivative incorrectly.. Apr10 comment Partial Differential Equations well you would have $c_1e^{At}$ which is just $cos(x)e^{sin(x)t}$. Would that be right? Mar18 comment Logistic Equation with MatLab @Amzoti if I made 1 .m file called logistic.m that contained the equation (with $a$ and $b$ being global) while I had another .m file that called the logistic file, should I use ode45? Mar6 comment Linear Constant Coefficient Different Equation @LutzL well now I know what to do but not how to do it. I'm about to just give up on this problem Mar6 comment Linear Constant Coefficient Different Equation @LutzL I'm understand a little better but I'm still not sure how to answer even part $(a)$ Mar5 comment Linear Constant Coefficient Different Equation @LutzL so I can make up any constant value? Just pick something like $0$ and $1$ for $N_0$ and $N_1$ respectively? Feb19 comment Compound Growth Okay I see what you're getting at. But in this case what is the difference between $N(t)$ and $N(t+\Delta t)$? Feb17 comment Population Growth - Ecology @satishramanathan nope, that is everything written in the problem. That's why I'm confused as well Feb10 comment Pendulum with angular velocity is there no mathematics behind this?
