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.

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?
Another SO question...

You should not ever consider Cramer's rule to solve a linear system to solve a linear system.

We are using a programming language that does not have a linear regression function in it. We have already implemented a single variable linear equation:
y = Ax + B
and have simply calculated the A and B coefficents from the data using a solution similar...

Here's.
linear equations
k = aX1 + bY1 + cZ1 k = aX2 + bY2 + cZ2 k = aX3 + bY3 + cZ3
What you can doYes, it's an easy linear algebra problem if you think of it the way Gil Strang does it.

How can I validate linear equations with regular expressions or is there another way besides using regular expressions. I will use ^ to denote an exponent.
2x + 3 = 8 //This should validate fine
3x + 2y + 4z = 12 //This should validate fine
4x^2 + 2y ...

You might.
I'd start by writing a definition of a valid linear equation a parser that would only generate a parse tree if the input was a valid linear equation.
Name, then of course this all crumbles.

Hi,
I needed an application for solving linear systems of equations (N up to 10), so I got different codes, and compile them, and they seem to work, but I get lots of problems with precision. I mean, the solvers are really very sensitive to small changes...

GNU Octave is essentially a free version of Matlab (the syntax is identical for basic operations), so you can try things out there and see how they compare to the answers that you're getting .

There are lots of different methods you can apply to solve linear systems combinatorical problems (picking one element out of a finite set).

Linear equations?m/2-8=10+m? And 2p-3=5-p/2
I dont really understand linear equations right now can you help me step by step?

Answer Snippets (Read the full thread at yahoo):
M/2 - 8 = 10 + m multiply though by 2 to handle the fraction
m - 16 = 20 + 2m collect letter terms to one side and numbers to the other
m - 2m = 20 + 16
-m = 36 m/2-8= 10+m
-m/2=18
m=-36
and
2p-3= 5-p/2
5p/2 = 8
p=16/5 .

You can create solutions using equations are not homogeneous, and superposition does not apply.
Linear equations are homogeneous, and superposition applies.
