| I have written an error function to compare simulated values to experimental data, but I also want to have a least squares fitting. I know that Mathematica has a function for it, I'm just not sure how that function can compare to what I want. The... |
| I am working in a system of 8 equations and am trying to solve for 8 variables. I ran NSolve[{equations},{vars},Reals], and it just spat out my equations back at me. Am I missing something or using this routine incorrectly? Any help would be... |
| I have a group of equations that I was solving pretty consistently with NDsolve. I added a couple more to add complexity to this model, and it all went haywire. I've stared at the code for a couple hours now and I have no idea where it went wrong.... |
| So I have a system of ODEs that I am solving through NDSolve, and I can plot them in mathematica, but I am curious how to get the x and y values used in the plotsfor manipulation in programs like excel. Here is the code I am currently working with.... |
| I have been working up a pretty simple code and I keep running up against an error saying input isn't a differential equation. Any help would be much appreciated. Clear["Global'*"]; ka = .2; kd = .02; km = 150; ns = 10; sens = 3; ro2 =... |
| I have two sets of code with equal parameters, but when I run the solver for changing nut incrementally, I get different solutions than the three points in my first code. Can anyone see a difference in either my equations or constants? ... |

| Having a problem with a loop I am running. The second row, last column value should be .130004, not the 10^11 value that I get. Any ideas on what is going on? Copied and pasted the body of code, but not the result table. Clear["Global'*"]; ... |
| I am having trouble with this loop I am running. For the second row, the last column should be reading .130004, but instead it is reading a value on the order of 10^11. I believe I have comitted a logic error in assigning something but can't figure... |
