Question

PLEASE USE MATLAB

Create a single MatLab script that On a single line (Line 1), defines matrix A such that A = 1 2 4. 5 7 8 Suppress the echo of A. On a single line (Line 2), use the size function to echo the size of A. On a single line (Line 3), use the length function to echo the length of the entire first row of A. On a single line (Line 4), use linear index notation to set the element located at row 3, column 2 of A to 0. Suppress the echo On a single line (Line 5), use subscript notation to set the element located at row 1, column 3 of A to -1. Suppress the echo.

Answer 1

A=[1 2 3;4 5 6;7 8 9]; % Define matrix A and supress the eco
SIZE=size(A) % Determine the size of matrix
LENGTH=length(A(1,:)) % Determine the length of first row vector
A(3,2)=0; % Set 3rd row and 2nd column element to 0
A(1,3)=-1; % Set first row and 3rd row element to -1
newA=A

OUTPUT--------------------------------------------------------------------------

SIZE =

   3   3

LENGTH =  3
newA =

   1   2  -1
   4   5   6
   7   0   9
