I want to compare first 10 data with the next 10 data using a while loop. I have coded for first 10 values and have obtained the plot. In the same way I need to obtain it for next 10 sets of values until 100 sets of values are completed. For this I need to code using i,j values something in this format x = a(j:j+1). Please help me with this code

clc;
close all;
x = a(1:11)
while n < 12
    y(n) = a(n) - a(n-1);
    n = n + 1
end
plot(y)

According to the text of the question (but not the posted code):

A = rand(100, 1);
B = reshape(A, 10, 10);
C = diff(B, 1, 1);
plot(C)

while-loops are useful if the limits are determined dynamically. Use a for-loop for known limits or a “vectorised” approach using arrays as above.

@Jan Thank you for your efforts. Let's make a last try if you can understand it by this flowchart what I exactly want else no problem.

@Surabhi A S: You ignore my questions for clarificationsm but introduce new information ("Z positive for more than 5 points"), which do not match the formerly given details. The instruction "fall is detected" is not clear.

Of course I could try to guess, what you want, but this is neither efficient nor trustworthy.

Before you can write a program, you need a clear and clean idea of what you want to achieve.
