hey how can i make column output? (and not row vec)

% the function gets a vector of numbers (=vecOfNum) 
% and return output vector (=vecPrevMean),
% each element is the average of all previous elements. 
function [vecPrevMean]= vecMean(vecOfNum)
count=1; %count the amount of elements in the vector
sumNum=0; %sum the elements 
for i=1:length(vecOfNum);
   if iscolumn(vecOfNum)==0
  sumNum= sumNum+ vecOfNum(i);
  vecPrevMean(i)=sumNum./count;   
  count=count+1;
  elseif iscolumn(vecOfNum)==1
  sumNum= sumNum+ vecOfNum(i);
  vecPrevMean(i)=(sumNum./count)'; 
  count=count+1;
  end
    
end

在 MATLAB Online 中打开

vecPrevMean(i,1)=(sumNum./count)'; 
           %  ^---------change to this (note : preallocation is also important)

It represents column vector learn more about vectors . If my answer worked make sure to accept the answer, also see the answer in your previous question.
