I have some trouble on setting of n-linear equations in matlab.I don't know how can I declare in matlab.I need matlab code for setting of n-linear equations..

Here you can find great example: http://blogs.mathworks.com/pick/2007/09/13/matlab-basics-video-solving-linear-equations/ (video!)

You can write n-linear equations as one matrix equation to solve it.

What is the best way for me to render math equations on the web? I am familiar with LaTeX's math mode.

You options for converting to html, but they'll all typically end up rendering the actual equations best will depend a bit on what sort of content....
It turns out this is a bit of a pain .
Texvc can convert LaTeX math equations to png or HTML.

A colleague sent me a document created with Microsoft Office 2007 that contains equations. On her end, the document looks fine; however, on my end, the equations show up with these funky characters overlaid on them:
Why do these weird characters show ...

Example
A1: =a B1: =a
A2: =a B2: =b
A3: =a B3: =c
COUNTIF(A1:A3,"a") returns 3
COUNTIF(B1:B3,"b") returns 1
to count where first list =a and second list =b you can... .
I assume you only want to count when the list contains both items in the same position .

How can I make equations smaller in TeX? For example, I want to use the equation environment as follows:
\begin{equation} long equation here \end{equation}
but then it's displayed in a way that's too large to fit in the margin. I get around this by using...

But then it's displayed in amsmath: align and variations of it for aligning across lines, gather to gather multiple equations.
Align).
Can also use \notag on individual equations in an environment (e.g.

Equations with radical equations Algebra 2 ? √x + 4 = √ x - 1 + 1

Answer Snippets (Read the full thread at yahoo):
X + 4 = √x - 1 + 1
√x + 4 = √x
4 = 0, which is false so there is no solution
If you meant √(x + 4) = √(x - 1) + 1, then
(√(x + 4))^2 = (√(x - 1) + 1)^2
x + 4 = x - 1 + 2√(x - 1) + 1
4 = 2√(x - 1)
2 = √(x - 1)
4 = x - 1
x = 5 Could you use parentheses... .

I don't have a lot of experience with Matlab. I know that you can plot equations with 2 variables like this:
ezplot(f1) hold on ezplot(f2) hold off;
How would you plot three equations with three symbolic variables?
An example system would be:
x^2+y^2+...

To display all three equations together, you can do solutions for the system of equations..
This should display the upper half of a sphere.

I have a system of 22 linear equations (exactly 22 equations and 22 unknowns) which are dynamically generated in an Excel spreadsheet. Is there a way to have Excel solve the system and produce a value for each of the unknown variables?

I don't know in your second example, I think: the point is you want all equations to be numbered in the order.
In your second example, two equations are numbered as #1.
Not sure, but probably not.

Hello.
What is the usual method or algorithm used to plot implicit equations of 2 variables?
I am talking about equations such as,
sin(x*y)*y = 20
x*x - y*y = 1
Etc.
Does anyone know how Maple or Matlab do this? My target language is C#.
Many thanks!

It's fairly complex....
In a related question, someone also linked to the gnuplot source code .
Then you can run an algorithm like marching squares on the resulting 2D grid to draw iso-contours .
One way to do this is to sample the function on a regular, 2D grid .
