I have a mat file (matrix)with 36000X7 dim in Matlab and I want to delete every 2nd row from the matrix that would result in 18000X7 dim matrix. How to do that using Matlab?

Write a Matlab script to determine the positive roots of the equation:
x^3-7x^2cos(3x)+3=0

use Matlab for solving the following integral:
integral(-1 to 4)((1+5e^(-25x^2)/(1+x^2/25))dx.

In searching for the placement of a key x ̄ in a sorted array x(i), i = 1,2,...,n, binary search partitions the current search domain into two subdomains by always selecting the mid-point index n/2 (or (n+1)/2, if n is odd) of the array. Clearly, binary search does not take into consideration the key value x ̄ in selecting this mid-point.
A simple variation of binary search, called interpolation search, is based on partitioning the current search domain such that the “mid-point” index is guessed by assuming a linear interpolation of the indices between the first key value x(1) and last key value x(n).
create a new function isearch which implements the
interpolation search algorithm.

Use Matlab to:
Create a function that accepts two numbers as input and returns 1 if the second divides the first, and 0 otherwise.
◦Bonus points if you make the function work with matrix inputs (and give a matrix output).

Hello, I would like to know how I can get a current-voltage-curve from the maximum points of the crrent and the voltage?

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?
