Open in MATLAB Online I'm providing another solution to address the longer summation you have posted in my first answer. Please let me know if this suits your needs: data = load('ex1data1.txt'); y = data(:, 2); m = length(y); ...
In summary: summation of a 1xN array A: sum(A); summation of all elements of a MxN array A: sum(A(:)) or sum(A,'all') (the latter works on the newer versions of MatLab only) I would anyway suggest checking the following documentation https://it.mathworks.com/help/matlab/ref/...

Example 1: Simple Array Summation With a Loop Let’s begin with a straightforward example: array=[1,2,3,4,5];totalSum=0;fori=1:length(array)totalSum=totalSum+array(i);enddisp(totalSum); In this example, we use a loop to iterate through each element of the array[1, 2, 3, 4,...
Sum the Elements of a Matrix Using thesum()Function in MATLAB To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we...
