@Paulo: You are right. The matrix oriented design of Matlab is easier to understand with a knowledge of vector algebra. It will take longer than a week to be familiar with the object oriented methods, if you never worked with OO before.

For new matlab/simulink users, do you know about the (interactive) video tutorials?!
No warranty about learning faster but the tutorials do help, the documentation is awesome and you should use it and learn by yourself.

The documentation has some limitations, e.g. MPOWER(scalar, matrix) is not explained sufficiently. Without deeper education in signal processing the Signal Processing Toolbox has a limited use only. The different filters are described well, but if you do not know, what you are searching for, there is no chance to solve a scientific problem. Nevertheless, it was not the interntion of the documentation to replace WikiPedia and the necessary lessons at the university. Therefore I agree with your estimation "awsome". Most of all if the M-source codes of the toolbox functions are taken as advanced examples. +1

Found this on the Link Exchange. http://www.mathworks.com/matlabcentral/linkexchange/links/2920-learn-matlab-in-30-minutes Maybe you might give it a shot.

Jan: I have no idea - I didn't actually try the link myself, I just threw it out there for whatever it's worth (which apparently is not much). Honestly, I have yet to see code that's as explicit and well documented as my own, and the quality of what's posted in the File Exchange is usually way below my standards. The authors' algorithms may be good but almost always they write cryptic, hard -to-follow code with few if any comments. I'm sure you'd agree. Apparently it does take more than 30 minutes to learn, and some people never learn to write robust, maintainable, well documented code even after decades. I hope none of those people ever go to work for Boeing or Airbus, or a medical equipment manufacturer, or a nuclear power plant.

@Image Analyst: You do know, that programmers with limited skill are working in sensitive areas. They let the ArianeV explode by confusing DOUBLE values and FLOAT overflow values - an epic 2.0e9 $ fault. A German health insurance had developped a new software, which solved all tests for a data set of 100 patients. To the big surprise of the managers it was absolutely impossible to expand the data base to 5.000.000 patients, because the fundamental concept resulted in an exponential growth of the latency. 25e6 $ burnt.
The list of dilettantish software tragedies could fill some books, but I stop here. My conclusion is, that a software can never replace savvy and common sense.

  • Read the "Getting Started" chapters in the documentation. They are designed to assist newcomers.
  • Read the help and doc texts whenever you have difficulties with a specific command.
  • Use the debugger if problems occur. See "doc debug".
  • Read the error messages twice. They contain important information
  • Avoid common pitfalls: Read the FAQ before the problems have a chance to occur. Most of all:
  • Do not use names, which contain indices like A1, A2, A3, ... Better use e.g. a cell array A{1}, A{2}, A{3}, because you can access it using an index.
  • You do not need EVAL - it produces just troubles. The only exception is getting numerical values for symbolic expressions. But for all other cases: Use a better EVAL-free solution.
  • Do not expect 0.3 - 0.2 - 0.1 to be zero. Floating point values have a limited precision, such that -2.776e-17 is not wrong.

@deep: And locally on your computer, typing "help" in the command window shows a short help, "doc" opens the full documentation. Try "help sin", "doc plot".

You can now get started in MATLAB by taking the free MATLAB Onramp. It teaches you the basics of MATLAB interactively -- you actually try out the MATLAB code and you see the results and feedback to help you
