Matlab Demonstration for Beginners

[TheAlbro2008]

Tha,k for this video

it will be great if you make a demonstraion to explain hox to write a program

[greatSephi]

well done....very useful for me.

[dElogics]

Thanks for your rubbish Microsoft monopolistic tutorial.

[jakeblanchard]

@dElogics

Interesting. Matlab runs on OS X and Linux, so I'm not sure why you would make such a comment.

[dElogics]

@jakeblanchard

We have octave also.

[jakeblanchard]

@dElogics

I agree that Octave is worth a look. It's an excellent alternative to Matlab and many Matlab scripts will run without modification in Octave.

[dElogics]

@jakeblanchard

I'll be glad, it's opensourced.

[repsieximo]

better but very basic for someone who want to run a monte carlo! it is more matlab intro than monte intro

[saisrinivas1989]

what should be the system configuration to run matlab? plz help..

[jakeblanchard]

@saisrinivas1989

It runs on Windows, Mac, and Linux. Either 32 or 64 bit. Requirements are minimal: 1 GB RAM, etc. If cost is an issue, try Octave (just Google it).

[artistdigital]

Which version of Matlab should I use?

[jakeblanchard]

@artistdigital

For a beginner, there isn't much difference from version to version. Just use whatever you can get access to.

Pls in Qpsk modulation. Ive generated the source bits with s=rand(1,200)>0.5; mapped 2 bits to on Qpsk symbol with Qpsk=sqrt(Es)*sqrt(0.5)*((1-2*­s(1:2:200))+1j*(1-2*s(2:2:200)­)) for Es=1 and plot(Qpsk,'+'),grid on. I added noise to Qpsk as n=(randn(1,100)+randn(1,100)*1­j)./sqrt(2); and Transmited signal, TX=Qpsk+n and I ploted TX,for Es=1,10 and 100. Please how do i demodulation using the minimum distance detection algorithm to reproduce the binary bits. Help me and thank you+God bless...Ty

[jakeblanchard]

@affexty

I don't know anything about demodulation. I would have to do some research. There is stuff on this algorithm out on the internet. Have you tried Google?

[affexty]

@jakeblanchard -Thanks for your reply,I've check google and I'm getting some ideas but the progress is slow as I'm still very new to Matlab...

[jakeblanchard]

@affexty

OK. Let me know if you have questions.

[ameersabergowayed]

please I want plot or solve this function in matlab for rc=1;

w=0:2; b=1/(3+i(w*rc-(1/w*rc)))

thanx

[jakeblanchard]

@ameersabergowayed

Is i a complex number? If so, do you want to plot the magnitude of b?

[ameersabergowayed]

@jakeblanchard yes this is a copmlex function (i or j )

[jakeblanchard]

@ameersabergowayed

Something like this would work. It plots a list of b values in the complex plane. That is, it plots the real part of b vs the imaginart part of b.

rc=1;

w=0:0.01:2;

b=1./(3+i*(w*rc-(1./(w*rc))));

plot(b)

thank you

[nnostalgy]

very important for anybody

thanks very much ..........

[durbanknight1986]

Hi

Does anyone know how I can have a multicolour line plot in matlab.Say for Temperature data where just one set of data is being plotted agaonst time.Above a certain temp I want the line colour to change.I cannot find a good example anywhere,someone please help.

[deedee7320]

Hi everyone! I am new to Matlab and the teacher who teaches it so arrogant and goes so fast and I feel stupid asking questions...I need some help with my homework...we did some stuff in class and now we have to look at it and write about it and I have zero clue where to start...Please if you wanna help please let me know :)

[irfaanfr1]

@deedee7320 ok!

[heloitsadi]

very nice tutorial...

[edga69]

Lots of useful info!

How do I select specific of elements from a vector or apply rules to a new vector, based on elements in a previous one? e.g. v1=[1 2 8 4]

and i want v2=[v(1)+v(2) v(2)+v(3)...up to v(length(v)-1)+v(length(v))].

[jakeblanchard]

I'm sure there are a variety of ways to do this. This works, but is not elegant:

v1=[1 2 8 4]

va=[0 v1];

vb=[v1 0];

v2=va+vb;

v2=v2(2:4)

[edga69]

thanks a lot. i was doing the same until the last line, when it went wrong when i was trying to generalise.

thanks very much

[patopillo2000]

thank you man

[desidude006]

You just summarized the first 4 lectures of Matlab for me.

Thanks!

[sayienmalangi]

thats gr8. thanks!

[muhmahfud]

thanks alots

its helpful as beginner for matlab

[ZombieJesusBrainz]

THANKS! its great people are motivated to help others learn on the tube!

[shanshui281]

thank you very much !

[rossito]

Thank you for that :) It's really helpful ...had things our tutor never showed us :D

[24karatbrain]

Thanks for the useful demo, Mr. Blanchard!

I need to plot about 1,000 points, the coordinates of which are in a 3-column text file: 1st column the x-, 2nd column the y-, and the third column the z-coodinates. What is the best way to input them into MatLab for plotting? Thanks, Mr. Blanchard!!!
