is referencing elements in a column array the same as for a row array? ie will a(3) return the third element of 'a', regardless if 'a' is a row or column array?

Hi,sorry for my bad english;
Let f[x_]=x^2
I want to integrate numerically this function,by Trapezoidal approach on interval[0,10] and my solution is like this
xold=0;h=0.01;xnew=h;sumution=0;While[xnew<10,sumution=sumution+h/2*(f[xold]+f[xnew]);
xold=xnew;xnew=xnew+h];Print[sumution]
This code gives me alist of datas and I want to plot this datas versus x;how can I do this?plz help me

Hi

I just need a little help with matlab

say if you have an array [2 5 10]

and you have a result from a different function say y=8

and want to find which numbers of the array have the same highest binary digit with y in the case
above y=[1000] and 2=[0010] 5=[0101] 10=[1010] so the only number in the array which has the same highest binary digit with 8 is 10.

How can i do this in matlab?

Is it possible you to implement the DVB-T2 transmitter (support MIMO-OFDM) and receiver in matlab?

Can you do a project with matlab about the Chernobyl Disaster? What I need for the research is about the radiation released and the life-time of the radiation released. That is not a mathematic question, you have to research and find data for that, load the data in matlab and plot those chemicals released.

In plot function we can choose the steps between numbers ! like x=0: 0.01 :1 ! here i choose 0.01
can i do something like that in Ezplot function ?! i have a plot in nano scale! and when i plot it with ezplot it shoes me continues straight lines! it's not smooth . how can i solve this??

Hi experts, i wonder if you can help me in my project which is an application for 3D modeling of satellite data geographical using Matlab, i have to add more options and functions to my application that can be useful for those how are in the Civil Engineering domain or even for example include a flight simulator and more. so I'm going to use satellite images 2D and 3D (some of them have the extension DEM). in fact my project idea is similar a little bit to GOOGLE EARTH with the it's options, but I'm going to focus just on a special area.
Hope you can help me and guide me to realize this work.
Special Thank to all the experts.

Find a more accurate formula for f '(t) using method of undetermined coefficient. Let's say
formula is of the form
f0(t) = A*f(t + 2h) + B*f(t + h) - B*f(t - h) - A*f(t - 2h)
Find the values of A and B such that error is minimized. What power of h is the error proportional
to? Use this formula to d/dx sin(x) at x = pi=3. Tabulate errors for different values of h.
