Matlab-Intro

1. Define a rectangular matrix with 5 rows and 6 columns as a MATLAB variable ‘A ’as A=[2 2 8 7 9 6;4 6 9 80 5 6;3 95 2 4 5 25;1 3 7 5 13 15;5 10 15 20 25 30;9 18 27 36 45 54].
2. Find sine of the define variable ‘A ’.
3. Find maximum value in each row and each column of ‘A ’using single MATLAB command.
4. Find maximum value in entire ‘A ’and location of rows/column of its occurance.
5. Using single MATLAB command sort 3 column in descending order without altering other columns of matrix.
6. Construct a matrix ‘B ’whose columns are cumulative sums of the columns of ‘A ’.
7. Create a vector ‘X ’containing elements from fifth and second column of ‘A ’.
