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.

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.

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 .

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 ...

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.

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 have a few equations that appear in a floating figure. Unfortunately, the corresponding equation numbers are assigned assuming that the float (and hence the equations) appear in the position that the float was defined. Conceptually, a page will appear...

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 .
