How do I split a column into a set group? (MATLAB beginner, help would be appreciated).

Hi,

I have a large list of numbers in a column i.e. (5;6;7;8 etc).

I want to split the column into segments where each segment has 60 numbers. Then I want to find the variance of each of those segments and see if its above a particular threshold.(And if its above a threshold then assign 1 into another new list which i have created before hand and have not included here.)

I have made it into a loop as this is what is required.

This is what I have so far:

for k = 1:num_segments

if var(vec_acc_total(:, (60*k)-59:60*k)>threshold

walking_segments_loop(k)=1

else

walking_segments_loop(k)=0

Any help would be appreciated as i am very new to matlab.

THank you!

solution:

listofnumbers=rand(360,1);%put your list here
threshold=0.08; %your threshold here
walking_segments_loop=(var(reshape(listofnumbers,60,[]))>threshold)' %here your new list
