I have written a code to calculate the end grade(sum) while dropping the lowest grade value between a specific number of columns in a matrix. My current code will be written below. I get the error assignment has more non-singleton rhs dimensions than non-singleton subscripts. Thanks in advance.

function updatedGrades = computeTotal(sectionGrades)

sectionGrades(:,end+1) = sum(sectionGrades(:,3:8),2)-min(sectionGrades(:,3:8),2)+sum(sectionGrades(:,9:10),2);
