Question

How do you perform these operations on the software MATLAB?

2. Create the following matrix A:

(a) Create a matrix B by extracting the first column of matrix A.

(b) Create a matrix C by extracting the second row of matrix A.

(c) Use colon operator to create a matrix D by extracting the first through third columns of matrix A.

(d) Create a singled valued matrix E by extracting the value from second row, third column of matrix A i.e. A2,3.

(e) Create a matrix F by extracting the values of elements A1,3 , A2,4 , and A3,5 and combining them into a single matrix.

Explanation / Answer

A = [3.4 2.1 0.5 6.5 4.2; 4.2 7.7 3.4 4.5 3.9; 8.9 8.3 1.5 3.4 3.9]

A has only 15 elements, so there's no A24 or A35, unless you mean A(2,4) and A(3,5), and that's different...

B = [A(1,3) A(2,4) A(3,5)]'
C = [A B]
