Is there a way to obtain the order of an ODE in mathematica.

For example, if i have `y''+5y`

i want mathematica return `2`

(beacuse it's a 2nd order equation). So, is it possible what i'm asking?

here is a way to extract the value automatically:

```
ode = y'' + y' + y == 0 ;
Max[Cases[ ode , Derivative[n_][y] :> n , Infinity]]
```

2

note this just finds the largest derivative in the expression, it doesn't verify if the expression is actually an ode..

Here you go: public static String reverseName (String name) { name = name.trim(); StringBuilder reversedNameBuilder = new StringBuilder(); StringBuilder subNameBuilder = new StringBuilder(); for (int i = 0; i < name.length(); i++) { char currentChar = name.charAt(i); if (currentChar != ' ' && currentChar != '-') { subNameBuilder.append(currentChar); } else...

At first the vectors in C# are called Arrays ;-) In a nutshell you are comparing products with the wrong prices. But why? Let me show this with an example: There are two important arrays: drycker: Prices: Cola -> 25 Fanta -> 20 Sprite -> 30 When you compare Cola...

A batch file solution isn't much fun, because batch can't really count or deal with arrays and indexes, it needs to work like: setup a counter, list the files, count through them, when the count matches the number you want, do something. @echo off setlocal enabledelayedexpansion set i=0 for %%f...

The problem is the 'inexact' floating point value of W=1.2. If you use W=12/10 you get a result. Note in this case you actually get a faster/cleaner result if you leave all the numeric values out except for X until after integration: Clear[d,W,Rm,X]; f = 1/(1 - R^2/Rm^2); A =...

It seems my mistake could only affect things if the one "min" object was compared to itself. Not quite. It could also be caused if there were two different "min" objects. In the case of the list sorted this particular time, it can only happen if the item is...

Perhaps you could use a legal-style paragraph numbering.: 1, 1.12, 1.12.1, 1.12.2, 1.12.2.5 and so on. You can always insert a new entity between existing entities by extending to a new level of '.1'. Quite how you stop users assigning absurdly high priorities to otherwise routine documents is another problem....

Edit to reflect clarification in comments: To sort an aggregation by string value use an intrinsic sort, however sorting on non numeric metric aggregations is not currently supported. "aggs" : { "order_by_title" : { "terms" : { "field" : "title", "order": { "_term" : "asc" } } } } ...

You cannot get the documents enumerated with position right from MongoDB. Thus that your manual job to do. The second problem is getting the neighbours. If you knew in advance the position of the required document, say i, you could do just .skip(i - 1).limit(3), and would get your neighbours...

In Lua, the order that pairs iterates through the keys is unspecified. However you can save the order in which items are added in an array-style table and use ipairs (which has a defined order for iterating keys in an array). To help with that you can create your own...

Presumably, ascending order. :) Kidding. If you mean "order of magnitude", the following solution will be O(m+n) or O(max(m,n)) where m is l1.length and n is l2.length. Algorithm: Keep a pointer to each linked list, step through both, and add the lesser of the two elements. If the elements are...

The straight forward solution in this specific case is to use sortBy on the tuples, modified on the fly to "invert" the first and second elements so that in the end the ordering is reversed: val a = Array((false, 8, "zz"), (false,3, "bb"), (true, 5, "cc"),(false, 3,"dd")) a.sortBy{ case (x,y,z)...

You may utilize integer part of the table to store keys in order: function add(t, k, v, ...) if k ~= nil then t[k] = v t[#t+1] = k return add(t, ...) end return t end t = add({ }, "A", "hi", "B", "my", "C", "name", "D", "is") for i,k...

Since you are specifying the ordinal domain, dc.js will used that instead of calculating it using the existing values and the ordering you specify.
