MATLAB: How to find average of each column in every matrix within a cell

averagecellmatrixmean

I have a 1×20 cell called "transmission" and I would like to find the average of each column (separately) within each matrix in the cell. Each matrix is 12000×20

Best Answer

mn=cellfun(@mean,c,'uniform',0);   % c is the cell array

mean operates by column by default.

MATLAB: Average

data - your array [42x16384]

EDIT

out = mean(reshape(data,size(data,1),[],8),3);

eg:

data - your array [55x72000]

out = mean(reshape(data,size(data,1),[],3),3);

out = squeeze(mean(reshape(data,size(data,1),3,[]),2)) ;

MATLAB: Averaging Together Every N Columns

This solution using the filter() command calculates interim results way beyond your need, but it's fast:

% Put in some pretend data
r = rand(16,10000);
% Define number of columns to average
AVG_COLS = 1000;
% Dimension over which to average
DIM = 2; % Columns
% Use filter to calculate the moving average across EVERY combination of columns
r_moving_avg = filter(ones(1,AVG_COLS)/AVG_COLS,1,r,[],DIM);
% Grab only the column averages that were actually wanted
r_avg = r_moving_avg(:,AVG_COLS:AVG_COLS:end)
