| I agree. And PlotGrid is a very good example. |
| Bill, That is very nice. I will remember that! |
| It may be that the integral does not exist. If so, you can still obtain numerical results: int[Delta_, J_] := NIntegrate[ Sqrt[(2*Delta*J*(3 - Cos[Pi*x] - Cos[Pi*y] - Cos[Pi*z]) + J^2*(3 - Cos[Pi*x] - Cos[Pi*y] -... |
| Yes -- easy for Mathematica: (* the list of equations *) eqs = { d - g == a (d - 1) + b (d - 1)^2 + c (d - 1)^3, e - h == a (e - 1) + b (e - 1)^2 + c (e - 1)^3, f - j == a (f - 1) + b (f - 1)^2 + c (f - 1)^3 ... |
| You can import the Excel sheet and plot the points or a surface, or both together: data = Rest@ Import["F:\\Users\\David\\Documents\\Mathematica Files\\Wolfram \ Forum\\Lawton\\Turnaround Elevation.xlsx"][[1]]; ... |
| Hi Laurens, you can turn off the warming message. I updated my answer to demonstrate. You could also suppress all messages with Quiet[], but that would suppress other error messages as well. |
| Thanks, Marvin. That works. |
| I have the same question. I see this received no answers so I’d like to reawaken it |
| The DiracDeta function is really not a function, it is a distribution. DiracDelta[0] does not have a value. It is defined by its effect under integration, which Mathematica performs correctly: Integrate[f[x] DiracDelta[x - a], {x, -Infinity,... |
| I agree with Szabolcs. The last two releases have broken the same code for me. The first time it was due to changes in FITS image import. This time it’s changes to rasterization. I am trying to do real work and need more attention paid to quality... |
