PLEASE WRITE DOWN THE CODE THEN RUN IT, AND GIVE ME THE OUTPUT

7. Common functions and indexing. Make cSum the column-wise sum of cMat. The answer should be a row vector (use sum) a. b. Make eMean the mean across the rows of eMat. The answer should be a column (use mean) c. Replace the top row of eMat with [11 d. Make cSub the submatrix of cMat that only contains rows 2 through 9 and columns 2 through 9 e. Make the vector lin=[1 2 20] (the integers from 1 to 20), and then make -2 3--20] every other value in it negative to get lin Make r a 1x5 vector using rand. Find the elements that have values
