it's a MATLAB course and I need coding and output for each steps

Compute and execute the following commands: 1) Define variables x1;x2;x3 and assign them the following values 3;6;9. 2) Define a row vector X1 with elements x1; x2;x3. 3) Define a column vector X2 with elements x1; x2;x3. 4) X1 is a row with numbers ranging from 1 to 20 , incremented by 1 . 5) X2 is a row with numbers ranging from 1 to 10 , incremented by 2 . 6) Define Matrix C, where C=1.10.61.33.21.10.63.40.65.50.63.10.0 Then, execute the following: A. C(2) : B. C(;; end ) : C. C(2;:) : D. C(1:2; end ) : E. diag(C) : F. Extract the first row. G. Extract the first column. H. Extract the last two rows of the matrix. I. Find the transpose of the matrix. J. Compute rank(C)
