Whether a name is a built in constant or not can be checked by the statement ''which -all <name>''. 2. Type the following vector in the command window: a) 𝐴= 123 b) 𝐵= 01−2−3 c) 𝐶= −120410−2106 i) Use MATLAB to find the value in the second row and the third column of matrix C. ii) Use MATLAB to find the second row of matrix C. iii) Use MATLAB to find the third column of matrix C. iv) Use MATLAB to delete the second column of matrix C. 3. You can also perform Element-wise assignment of the Matrix elements. a) >> A(1,1)=1; b) >> A_r1=[1 2]; c) >> e_col1=[1;3.7;8]; >> A(2,1)=3.7; >> A_r2=[3.7 -0.002]; >> e_col2=[2;2e-3;1.3e5]; >> A(1,2)=2; >> A_r3=[8 13000]; >> e_col3=[5;1.3e7;
