I got this tutorial from the website below; 
http://www.ee.nmt.edu/~rison/ee389_spr08/ 
I am having difficulty with the questions on the last page.
I have downloaded all the files from the website. I am new to Matlab. Can import the toa_data.dat file.

also which are the linear equations and which are the non linear equations?

please help with tutorial on hyperbola, multilateration and errors (pdf attached)

The Math / Science topic primarily includes discussions of mathematics, physics, statistics and economic analysis, but also biology, chemistry and other sciences.

Math / Science

MATLAB is a numerical computing environment and proprietary fourth-generation programming language. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, Fortran and Python. Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the MuPAD symbolic engine, allowing access to symbolic computing capabilities. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems.
