MATLAB: Average of matrix element average of matrix element Suppose i have a 4X1 matrix like [a;b;c;d]. Now i want the output as [a;(a+b)/2;(a+b+c)/3;(a+b+c+d)/4]. How to do that? Best Answer x = [a;b;c;d];cumsum(x) ./ (1:numel(x)) Related SolutionsMATLAB: Create a matrix with existing matrix C and D have same number of rows. Similarly A and B have same number of rows. So C to D is straightforward since number of rows in C and D are equal, and D has 4 times the columns in C.D=repmat(C,1,4)and for A to B you can use this workaround.B=repmat(A,1,10)B=B(:,1:3600);I hope someone gives a straighter solution.
