MATLAB: Array average every 30 values

array

Hi again,

I have an Array of 1440×31 and I would like to get another Array, that's calculates the average of every 30 elements (of each row), so finally the array will be 48×31. I had a similar question but struggling to find it again,

thanks!

Best Answer

squeeze(mean(reshape(A,30,48,31)))

Assuming A is the matrix

Assumming the number of elements of the vectors is a multiple of n, reshape the vector in columns of n rows and take the mean across the rows:

assert(mod(numel(A), n) == 0, 'number of elements of A is not a multiple of n');
result = mean(reshape(A, n, []), 1)

The final matrix should be 31*30

out=squeeze(sum(reshape(A,31,30,[]),3)); % sum should be along 3rd dimension
