write separate functions arithmetic_mean(), rms_average(), harmonic_mean(),
geometric_mean() which takes the data array as the argument and compute the respective quantities.
Write a script averages which take two values xlow and xhigh and generate 10000 random numbers in
the range [xlow…xhigh], and calls the appropriate functions to compute arithmetic mean (average), rms average, geometric mean and harmonic mean. Flow Chart also.

Write a single program that calculates the arithmetic mean (average), rms average, geometric mean
and harmonic mean for a set of n positive numbers. Your program should take two values xlow and
xhigh and generate 10000 random numbers in the range [xlow…xhigh], and should print out arithmetic
mean (average), rms average, geometric mean and harmonic mean.
The definitions of means are given as follows.

If there is a group of n people in a room, what is the probability that two or more of them having same
birthday? It is possible to determine answer to this question by simulation. (Hint: You can generate
random dates, n times and determine the fraction of people who born in a given day). Write a function
that determines the answer to this question by simulation. The program you write can take n as the
input and prints out the probability that two or more of n people will have the same birthday for
n=2,3,4…. 40...Flow chart also.

The Birthday Problem: The birthday problem is stated as follows:

,I am trying to find peaks of whole Curve or graph or ECG .... but i dont know why in my code show peaks in y vector, while i need it in whole of ecg

If someone could point me in the right direction it would be greatly appriciated.

x = load ('C:\ekg\example_ecg.txt'); y= x ( : , 2); [pks,locs] = findpeaks(y); plot (y); hold on ; plot(pks,y(locs),'rv','MarkerFaceColor','r' ); grid on

Solve the following systems of equations using both the matrix left divison and the inverse matrix methods:

(a) -2x1 + x2 = -3
x1 + x2 = 3

(b) 10x1 - 7x2 + 0x3 = 7
-3x1 + 2x2 + 6x3 = 4
5x1 + x2 + 5x3 = 6

(c) x1+ 4x2 - X3 + X4 = 2
2x1+ 7x2 +x3 -2x4 = 16
x1 + 4x2 - x3 + 2x4 = -15
3x1 - 10x2 -2x3 + 5x4 = -15
