Hello all,

I collected the data from pressure mapping (matrix 16x10).

my data collection has matrix 25952x10 = (1622 x 16 x 10) = 27 x 60 x 16 x 10

16 is a row, 10 is a column, 27 is the sampling rate, 60 is sec(T) 1622 is an array.

I want to convert 27 arrays(16x10x27) to 1 segmentation(16x10) to find the center of mass.

finally, I want to average segmentation of 1 to 60 segmentation(16x10) to find the center of mass.

T = readmatrix('dataset.csv')

R = reshape(T.',size(T,2), 16, [])

P = permute(R,[2 1 3])

F = P(:,:,1:27)

szf= size(F);

Ft = sum(sum(F,1),2)

cy = sum((1:szf(1)).'.*sum(F,2))./Ft

cx = sum((1:szf(2)).*sum(F,1))./Ft

I was completed some code. some part not yet to convert from 27 arrays to 1 segmentation and average 60 segmentation.

I want to ask one question, Can you explain to me the Window length, sampling rate, and time? ( is it different or the same?).

Thank you in advance.
